專利名稱:分離的苛養(yǎng)木桿菌gum操縱子,分離的其核酸分子及它們的用途的制作方法
技術(shù)領(lǐng)域
本發(fā)明涉及到苛養(yǎng)木桿菌(Xylella fastidiosa)的操縱子的分離。尤其是其涉及到這樣的一個(gè)操縱子的分離,其包括九個(gè)基因,分別表示為xfgum B,C,D,E,F(xiàn),H,J,K及M。同樣作為本發(fā)明一部分的是這九個(gè)基因的每一個(gè)的分離的核酸分子。同樣作為本發(fā)明一部分的是含有可操作連接至啟動(dòng)子的該操縱子或一個(gè)或多個(gè)組分(component)基因的表達(dá)載體,含有該操縱子或一個(gè)或多個(gè)所述基因的重組細(xì)胞,這些基因的表達(dá)產(chǎn)物,及其各自不同的用途。
背景技術(shù)
黃原膠是一種由致植物病細(xì)菌野油菜黃單胞菌(Xanthomonas campestris(Ielpi等,1981,F(xiàn)EBS Lett.130253-256)產(chǎn)生的外多糖(下文稱"EPS"),野油菜黃單胞菌中這種胞外多糖的生物合成由一簇共12個(gè)基因,gumB-gumM(Becker等,1998,Appl Microbiol Biotechnol,50145-152;Vojnov等,1998,Microbiology 144487-493)所控制。其由聚合五糖重復(fù)單元所組成,該五糖單元是在多聚異戊烯醇磷酸酯載體上依次增加葡萄糖-1-磷酸,葡萄糖,甘露糖,葡萄糖醛酸,及甘露糖而成(Ielpi等,1993,J.Bacteriol.1752490-2500)。五糖重復(fù)單元還有不同程度的O-乙?;氨峄?Ielpi等,1993,J.Bacteriol.1752490-2500)。
使用一簇?cái)y帶gumB及gumC的基因進(jìn)行轉(zhuǎn)化,在缺陷型突變體中恢復(fù)了黃原膠的產(chǎn)生,這表明gumB及gumC都涉及到黃原膠跨細(xì)菌細(xì)胞膜的遷移(Vojnov等,1998,Microbiology 144487-493)。
有兩組基因涉及到黃原膠的生物合成一組是基因xpsIII,xps IV及xpsVI,它們分別負(fù)責(zé)合成UDP-葡萄糖,UDP-葡萄糖醛酸及GDP-甘露糖(Harding等,J.Bacteriol 1692854-2861(1987);Harding等,J.Gen Micobiol139447-457(1993);Hotte等,1999;Poplin等J.Bacteriol 174191-199(1992),1992),另一組是基因gum或xpsI,其編碼的酶參與了連接至多聚異戊烯醇磷酸酯的五糖的聚合及EPS向胞外介質(zhì)中的分泌(Ielpi等,1992;出處同上Ielpi等,1993出處同上)。
野油菜黃單胞菌的gum基因集中在一個(gè)大約長16Kb的操縱子(GUM操縱子)中,含有12個(gè)基因,它們是gumB,C,D,E,F(xiàn),G,H,I,J,K,L及M。gumD基因編碼葡糖基轉(zhuǎn)移酶I,其負(fù)責(zé)使UDP-葡萄糖的葡萄糖-1-磷酸轉(zhuǎn)移至polyprenol磷酸鹽載體上,以形成脂-單糖。GumM基因編碼葡糖基轉(zhuǎn)移酶II,其催化增加第二個(gè)葡萄糖殘基以形成脂-二糖。GumH基因編碼葡糖基轉(zhuǎn)移酶III,其催化增加第一個(gè)甘露糖殘基以形成脂-三糖。GumK基因編碼葡糖基轉(zhuǎn)移酶IV,其催化增加一個(gè)葡萄糖醛酸殘基以形成脂-四糖。GumI基因編碼葡糖基轉(zhuǎn)移酶V,其催化增加另一個(gè)甘露糖殘基以形成脂-五糖。GumF基因編碼乙酰轉(zhuǎn)移酶I,其催化內(nèi)部甘露糖殘基的乙酰化。GumG編碼乙酰轉(zhuǎn)移酶II,其催化外部甘露糖殘基的乙?;W詈?,gumL編碼丙酮酸縮酮轉(zhuǎn)移酶(pyruvate ketal transferase),其催化外部甘露糖殘基的丙酮酸化。GumB,C及E涉及到EPS通過細(xì)菌細(xì)胞膜的聚合及分泌,而gumJ被認(rèn)為參與了與EPS聚合及分泌平行的一個(gè)階段(Ielpi等,1992出處同上;Ielpi等,1993出處同上)。
黃原膠因?yàn)槠渥鳛楹芤旱脑稣硠┒哂袕V泛的商業(yè)用途。其應(yīng)用于食品及非食品工業(yè),還可作為懸浮液,乳液及泡沫的穩(wěn)定劑。在黃原膠生物合成途徑中有缺陷的黃單胞菌(Xanthomonas)突變株已經(jīng)表明可以合成并聚合具有不同結(jié)構(gòu),類似的流變學(xué)特性及不同的粘性的黃原膠(Hassler和Doherty,1990,Biotechnical Prog 6182-187)。乙酰化及丙酮酸化可影響黃原膠的粘性特征。丙酮酸的存在增加粘性而乙酸降低粘性(Hassler和Doherty,出處同上)。從黃原膠側(cè)鏈中減少糖殘基同樣可以影響粘性。與野生型黃原膠相比,缺乏末端甘露糖的聚合物(聚四體)是很弱的增粘劑。相比較來說,同時(shí)缺乏末端甘露糖及葡萄糖醛酸的聚合物(聚三體)是很好的增粘劑(Hassler和Doherty,出處同上)。一種非乙?;捏w和一種乙酰化四體,它們都缺乏側(cè)鏈末端甘露糖殘基,前一種在內(nèi)部甘露糖殘基上還缺乏乙酸基團(tuán),它們與野生型相比,前一種表現(xiàn)出較高粘性而后一種表現(xiàn)出較低粘性(Levy等,1996,Biopolymers 38251-272)。較高粘性與較低粘性的主要構(gòu)象差別是開放螺旋骨架數(shù)量的增加及側(cè)鏈可塑性高粘度的增加(Levy等,1996,Biopolymers 38251-272)。
黃原膠也可作為藥物穩(wěn)定劑使用,以提高藥物的吸收,延緩藥物的釋放,還可用于控釋制劑中(Talukdar等,1996,J Pharm Sci 185537-540)。與黃原膠混合的α-環(huán)糊精減少了直腸粘膜中以及肝臟的嗎啡的一過性代謝(first-pass metabolism),且表現(xiàn)出阿片樣物質(zhì)的表觀直腸生物可利用性提高了大約4倍(Kondo等,1996,Biol Pharm Bull 19280-286)。黃原膠藻酸鹽已被用于對酶的膠囊化。黃原膠藻酸鹽球體在最佳條件下重復(fù)使用20次后仍顯示出最大尿素酶活性的75%(Elcin,1995,Biomaterials 161157-1161)的活性。
使用水溶性食用纖維,黃原膠及刺槐豆多糖(locust bean gum)制備的持續(xù)釋放型水凝膠栓劑已顯示出比商品栓劑更長時(shí)間的持續(xù)的藥物釋放。平均滯留時(shí)間較長,在血漿濃度對時(shí)間的曲線下的面積未減少。組織病理學(xué)研究顯示出水凝膠栓劑對直腸粘膜的良好的生物安全性。這些結(jié)果表明,使用黃原膠和刺槐豆多糖制備的IMC水凝膠栓劑是一種實(shí)用的直腸試劑,它具有延長的效果且副作用減小(Watanabe等,1993,Bio Pharm Bull 16391-394)。
用黃原膠制備的水凝膠中,強(qiáng)地松龍(prednisolone)的表觀釋放速率隨著黃原膠濃度的增加而減少,表明藥物分子的擴(kuò)散主要受控于基質(zhì)中三維網(wǎng)狀結(jié)構(gòu)的密度。這些結(jié)果顯示,藥物釋放不僅受控于網(wǎng)狀結(jié)構(gòu)的密度,同時(shí)也受控于水凝膠的顯微粘性(Watanabe等,1992,Chem Pharm Bull 40459-462)。新霉素-呋喃唑酮-黃原膠復(fù)合體已被顯示可以增加藥物抗微生物的活性(Dumitriu等,1993,J.Biomater 7256-276)。
黃原膠還顯示可以緩解糖尿病。黃原膠給藥糖尿病患者后降低了空腹和進(jìn)食后的血清葡萄糖,也降低了空腹時(shí)的血漿總膽固醇水平。黃原膠還傾向于降低空腹和進(jìn)食后胃泌素及胃抑制多肽(GIP)的水平,總甘油三酯和VLDL甘油三酯的空腹水平,以及VLDL及LDL中的膽固醇空腹水平?;颊咴诔粤它S原膠松餅后有一種很飽的感覺而沒有嚴(yán)重的消化癥狀(Osilesi等,1985,Am J Clin Nutr 42597-603)。
幾種因素與致植物病細(xì)菌的致病性相關(guān),包括胞外酶的生產(chǎn),外多糖的生產(chǎn),毒素和植物生長素以及介導(dǎo)特定植物病原體相互作用的因子的生產(chǎn)(Agrios,1988,Plant Pathology,3rd edition,Academic Press;Alippi,1992,Agronomie 12115-122)。幾種細(xì)菌的致病性中,EPS的作用均為已知。其與以下相關(guān)(i)因?yàn)槟举|(zhì)管閉塞導(dǎo)致的細(xì)胞死亡,(ii)粘液損害以及(iii)輔助植物/病原體相互作用以及植物組織中細(xì)菌的生長。
幾個(gè)研究組已經(jīng)調(diào)查了黃單胞菌的致病性中黃原膠的作用。盡管很長一段時(shí)間以來人們認(rèn)為黃原膠對于致病性是很關(guān)鍵的,許多人并未成功證明該EPS與致病性之間有一個(gè)直接的聯(lián)系(Kamoun and Kado,1990,J.Bacteriol1725165-5172)。最近以來,已經(jīng)證明了黃原膠生物合成后期階段gum D的刪除(Chou等,1997,Biochem Biophys Res.Commun 233265-269)或改變(Katzen等,1998,J.Bacteriol 1801607-1617)減少了花椰菜中導(dǎo)致黑腐病的毒力及降低了黃單胞菌對植物體的進(jìn)攻性。盡管苛養(yǎng)木桿菌感染柑橘樹的癥狀已為公知,例如,葉子clorosis,營養(yǎng)缺陷的癥狀,果實(shí)體積的減小,等(DeNegri,1990,Com.Tec.No.82,Ext.Rural,Cats,Compinas;Malavolta等,1990,Cordeiropolis,v.11,n.1,p.15-18),細(xì)菌致病的機(jī)理尚不清楚。細(xì)菌感染有賴于昆蟲載體例如Oncometopia facialis,Acrogonia terminalis及Dilobopterus costalimai(Gravena等,1997,"Os vetores de X lellafastidiosa InClorose Variegada do Citros")。這些昆蟲,當(dāng)以木質(zhì)養(yǎng)料為食時(shí),將細(xì)菌引入其容易滋長的木質(zhì)管(Lopes等,1996,"Xvlella fastidiosa",F(xiàn)itopathologinBrasileira,Brasilia v.2 1,Suplemento p.343;Roberto等,1996,F(xiàn)itopatologiaBrasileira,Brasilia v.21,n.4,p.517-18)。由XfGUM操縱子合成的EPS,為本發(fā)明的一個(gè)特征,可能直接涉及到在柑橘樹中導(dǎo)致柑桔屬斑駁Clorosis的致病性及其他植物例如咖啡及葡萄植物中的其他疾病。
發(fā)明簡述本發(fā)明部分涉及大約12710個(gè)核苷酸的核酸分子,其編碼XfGUM操縱子的成員,包括xfgumB,xfgumC,xfgumD,xfgumE,xfgumF,xfgumH,xfgumJ,xfgumK及xfgumM的基因,本發(fā)明涉及該操縱子以及由此編碼的蛋白的用途。上述物質(zhì)可被用于例如控制柑橘樹疾病如柑桔斑駁Clorosis(CVC)及其它植物中的細(xì)菌導(dǎo)致的疾病。由XfGUM操縱子編碼的酶所產(chǎn)生的EPS可以導(dǎo)致由木質(zhì)管閉塞所引起的疾病或者通過細(xì)菌感染,粘附及擴(kuò)散機(jī)制所導(dǎo)致的疾病;然而申請人并不局限于上述任一理論。本發(fā)明也涉及到XfGUM操縱子的組分在生產(chǎn)外多糖方面的應(yīng)用,這種新多糖和該多糖的結(jié)構(gòu)變體的工業(yè)應(yīng)用和/或藥物用途,所用宿主為苛養(yǎng)木桿菌或其他細(xì)菌。
本發(fā)明的基礎(chǔ)是許多不曾預(yù)料及令人驚奇的發(fā)現(xiàn)。一個(gè)發(fā)現(xiàn)是一種長為12710個(gè)核苷酸的DNA序列存在于致植物病細(xì)菌苛養(yǎng)木桿菌的基因組中。而此前黃原膠操縱子僅在野油菜黃單胞菌中發(fā)現(xiàn)。另一個(gè)發(fā)現(xiàn)是XfGUM操縱子缺少基因gumI,gumG及gumL,它們分別編碼葡糖基轉(zhuǎn)移酶V,乙酰轉(zhuǎn)移酶II及丙酮酸縮酮轉(zhuǎn)移酶。這些基因的缺乏表明XfGUM操縱子編碼的酶對由四聚體單位所組成的外多糖的合成是必需的,所述四聚體單位含有葡萄糖,葡萄糖,甘露糖及葡萄糖醛酸。因?yàn)榫幋a乙酰轉(zhuǎn)移酶II及丙酮酸縮酮轉(zhuǎn)移酶的基因缺乏,所以產(chǎn)生的四糖并沒有丙酮酸化,且正如黃單胞菌中所證明的,其甘露糖是部分乙酰化的。這些結(jié)果表明XfGUM編碼的酶可以產(chǎn)生具有新的流變學(xué)及化學(xué)特性的新多糖。
本發(fā)明包括但并不限于,(a)含有編碼糖基轉(zhuǎn)移酶I,糖基轉(zhuǎn)移酶II,糖基轉(zhuǎn)移酶III,糖基轉(zhuǎn)移酶IV及乙酰轉(zhuǎn)移酶I的XfGUM操縱子的結(jié)構(gòu)區(qū)及調(diào)控區(qū)的核苷酸序列,以及下文稱GUMB,GUMC,GUME和GUMJ的蛋白;(b)上述核苷酸序列在細(xì)胞中的表達(dá);(c)分離的酶,蛋白及其活性形式,以及其突變體,片段及融合蛋白;(d)由GUM樣操縱子編碼的酶和/或蛋白在篩選方法中的用途,所述方法用以鑒定控制苛養(yǎng)木桿菌和/或相關(guān)的生物所致的疾病的化合物;(e)改造細(xì)菌宿主以表達(dá)由XfGUM所編碼的酶和/或蛋白;及(f)表達(dá)由XfGUM編碼的酶和/或蛋白的改造宿主在制備用于工業(yè)和/或醫(yī)療目的以及用于動(dòng)物包括人的外多糖方面的應(yīng)用。
附圖的簡要說明

圖1A-1I顯示了本發(fā)明蛋白的推導(dǎo)的氨基酸序列與野油菜黃單胞菌的同源蛋白的氨基酸序列的比較;圖2提出了一種使用本發(fā)明組分的生物合成途徑。
優(yōu)選技術(shù)方案的詳細(xì)說明本發(fā)明涉及苛養(yǎng)木桿菌基因組的大約12710個(gè)核苷酸的核酸分子,其編碼的XfGUM操縱子包括基因xfgumB,xfgumC,xfgumD,xfgumE,xfgumF,xfgumH,xfgumJ,xfgumK及xfgumM,本發(fā)明還涉及該操縱子作為DNA和其編碼的蛋白在控制柑橘樹疾病柑桔斑駁Clorosis(CVC)或由其它植物如櫟樹及葡萄中的細(xì)菌導(dǎo)致的相關(guān)疾病方面的作用。
下列定義以消除任何可能于說明書及權(quán)利要求書中產(chǎn)生的概念不清楚。
本發(fā)明所使用的“相似性”是指核苷酸序列的同一性,假如經(jīng)過總體對比后,較小序列的70%的核苷酸與其他序列的相應(yīng)核苷酸是同一的,那么可以說該序列與所述序列具有70%的同一性??傮w對比可以通過動(dòng)態(tài)程序的方式來完成(Thompson JD等(1997),Nucleic Acids Res.25,4876-4882引用本文作為參考)。這就保證了算數(shù)上的最佳對比,其為所有核苷酸之間的匹配與不匹配確定了數(shù)值,也為不同長度的插入或缺失的罰分確定了數(shù)值。常用的數(shù)值為1.9是匹配,0是不匹配,15是出現(xiàn)了缺口,6.66是該缺口的延伸。
實(shí)施例1使用標(biāo)準(zhǔn)技術(shù)包括使用限制性酶BamHI消化DNA從來自總苛養(yǎng)木桿菌的DNA制備粘粒文庫。大約為35-45千堿基對的片段被選為最相關(guān)片段。制備雜交圖譜以選擇不重疊的粘粒,挑選以后,使用識別的鳥槍法對其進(jìn)行測序。選定與黃單胞菌(Xanthomonas spp)序列類似的一個(gè)粘粒。大約12710個(gè)核苷酸的片段被分離且作進(jìn)一步研究。
實(shí)施例2對實(shí)施例1中的分離的核苷酸作進(jìn)一步的研究包括將12710個(gè)核苷酸的片段與已知的野油菜黃單胞菌的GUM操縱子進(jìn)行比較。該已知操縱子已被描述含有12個(gè)基因;然而本發(fā)明所揭示的操縱子卻顯示只含有9個(gè)基因,也就是說,其含有的基因與gumB,C,D,E,F(xiàn),H,J,K及M具有一定的同源性,然而并未發(fā)現(xiàn)與gumG,I或L同源的序列。
為了區(qū)別這兩組基因,做為本發(fā)明一部分的那些基因本文以下稱“xfgum”基因,該操縱子稱為“XfGUM”。
xfgumB,C,D,E,F(xiàn),H,J,K及M的核苷酸序列分別列于SEQ ID NO1-9。完整的XfGUM操縱子列于SEQ ID NO10。
xfgum基因所編碼的推導(dǎo)的氨基酸序列由序列SEQ ID NO11-19所述。已將其與野油菜黃單胞菌的相應(yīng)的氨基酸序列進(jìn)行了比較。圖1A-1I顯示同源性分析,其中使用的縮寫“GUMBXf,GUMCXf”等對應(yīng)于本發(fā)明所述的蛋白,而“GUMBXc,GUMCXc”等對應(yīng)于野油菜黃單胞菌的蛋白。
實(shí)施例3根據(jù)苛養(yǎng)木桿菌序列與野油菜黃單胞菌序列的同源性,得出有關(guān)編碼蛋白的功能的結(jié)論,并推測出苛養(yǎng)木桿菌合成黃原膠樣產(chǎn)物的機(jī)理,見圖2。具體地講,xfgumD編碼糖基轉(zhuǎn)移酶I類似物,其涉及到通過UDP-葡萄糖上的葡萄糖-I-磷酸轉(zhuǎn)移至異戊二烯醇載體上加入第一個(gè)葡萄糖殘基,結(jié)果產(chǎn)生脂質(zhì)單糖。該合成第二步涉及通過由xfgumM編碼的糖基轉(zhuǎn)移酶II類似物添加另一個(gè)葡萄糖殘基,結(jié)果產(chǎn)生脂質(zhì)二糖。隨后,認(rèn)為由xfgumH所編碼的糖基轉(zhuǎn)移酶III類似物添加一個(gè)甘露糖殘基以形成三糖,通過由xfgumK所編碼的糖基轉(zhuǎn)移酶IV類似物添加一個(gè)葡萄糖醛酸殘基以形成四糖。xfgumF基因編碼乙酰轉(zhuǎn)移酶I類似物,其如上所述催化甘露糖殘基的乙?;?。由xfgumB,C及E所編碼的蛋白顯示涉及通過細(xì)菌細(xì)胞膜的黃原膠樣EPS的分泌,而由xfgumJ所編碼的蛋白表現(xiàn)出涉及黃原膠樣EPS的聚合及分泌。
正如上所述,XfGUM操縱子缺乏對應(yīng)于黃單胞菌基因GUMG,I及L的組分,它們編碼乙酰轉(zhuǎn)移酶II,葡糖基轉(zhuǎn)移酶V,及丙酮酸轉(zhuǎn)移酶。這表明由苛養(yǎng)木桿菌所產(chǎn)生的EPS由葡萄糖-葡萄糖-甘露糖-葡萄糖醛酸四聚體單位組成,其中這些四聚體并未丙酮酸化但已全部或部分乙?;?br> Hassler等,Biotechnol Proj.6182-187(1990),及Levy等,Biopolymers38251-272(1996),都表明了黃單胞菌突變株黃原膠生物合成途徑(一步或多個(gè)步驟缺陷)可合成黃原膠的結(jié)構(gòu)變體,該變體具有的化學(xué)特性與其他的黃原膠結(jié)構(gòu)變體及標(biāo)準(zhǔn)的黃原膠不同。乙?;氨峄家阎梢杂绊扅S原膠的粘性特征。丙酮酸基增加了粘度而乙?;档土苏扯取8M(jìn)一步,末端甘露糖缺失時(shí),粘度降低。缺乏側(cè)鏈末端甘露糖的非乙酰化的四聚體具有較高的粘度。上述發(fā)現(xiàn)表明本文所述的EPS具有與先前鑒定的黃原膠不同的特性。
上述說明,包括實(shí)施例,描述了本發(fā)明的特征。這些包括編碼本文所述任一及所有xfgum蛋白(包括GUMxfB,C,D,E,F(xiàn),H,J,K及M)的分離的核酸分子,以及所述蛋白本身。尤其優(yōu)選,包括SEQ ID NO1-9所示的核苷酸序列或由SEQ ID NO1-9所示的核苷酸序列組成的分離的核酸分子,以及與這些核酸分子不同、但從遺傳密碼的簡并性角度來看、仍編碼具有SEQ ID NO11-19所示氨基酸序列的蛋白的核酸分子。
本發(fā)明分離的核酸分子包含在表達(dá)載體中,所述核酸分子可操作地連接至啟動(dòng)子上。根據(jù)本發(fā)明這一特征,本文所描述及要求保護(hù)的多個(gè)核酸分子可以包括在表達(dá)載體中。本文描述了9個(gè)核酸分子家族,這些家族核酸分子的任意及全部組合都可以成為該表達(dá)載體的一部分。換句話講,2,3,4,5,6,7,及8種該核酸分子的組合可以是這些載體的一部分,這些表達(dá)載體也可以包括所述9種核酸分子,或僅包括一種核酸分子。
同樣作為本發(fā)明一部分的是重組細(xì)胞,例如重組原核細(xì)胞株及重組真核細(xì)胞系,其已被一個(gè)或多個(gè)本發(fā)明的分離的核酸分子或重組表達(dá)載體轉(zhuǎn)化或轉(zhuǎn)染。
如本文所述,同樣作為本發(fā)明一部分的是分離的XfGUM操縱子。優(yōu)選的實(shí)施方案是SEQ ID NO10所示的序列;然而,可以理解上述遺傳密碼的簡并性同樣也適用于此。更進(jìn)一步,有關(guān)操縱子以及本文所述的所有核酸分子,優(yōu)選密碼子使用原則適用于應(yīng)用這些核酸分子轉(zhuǎn)化或轉(zhuǎn)染的細(xì)胞。
如前所述,同樣作為本發(fā)明的特征的是由分離的核酸分子編碼的蛋白。該蛋白如前所述具有酶的活性。更進(jìn)一步,其可以用作免疫原以產(chǎn)生抗體,不管是單克隆抗體還是多克隆抗體,其都可如以下所述進(jìn)行應(yīng)用。更進(jìn)一步,這些蛋白可以以不同的重組形式產(chǎn)生(包括融合蛋白),以活性形式產(chǎn)生,該活性形式的蛋白包含的氨基酸序列小于所述蛋白全部的氨基酸序列。例如,已知酶含有不同的結(jié)構(gòu)功能域,包括一個(gè)或多個(gè)活性位點(diǎn),所述活性位點(diǎn)是本發(fā)明的一部分,其含有本發(fā)明蛋白的小于全部的氨基酸序列。
如前所述,本發(fā)明的蛋白可用于制備黃原膠類似分子,例如圖2所示的,即[葡萄糖-葡萄糖-甘露糖-葡萄糖醛酸]n。其中n是一個(gè)從1至約5000的整數(shù),優(yōu)選從約300至大約5000,最優(yōu)選是大約1500-3000。
