中興大學生化研究所周三和老師的實驗室即是以結構生物學為導向,並輔以生物体的功能研究。目前主要從事兩個微生物結構基因体學的研究,一為重要的植物病原菌Xanthomonas campestris (黑腐菌), 希望從中找出此一致病菌的病理成因及新型的蛋白質折壘; 另一為感染人類並為一超級抗藥性的致病菌Stenotrophomonus maltophilia, 希望利用最新抑制細菌群聚現象(Quorum sensing)的觀念, 找出可抑制病原菌產生致病性因子的藥物。由於目前大部份病原病都已對現有的抗生素都已產生抗藥性, 故利用此一新觀念找尋新型抗生素為一極重要的研究項目。而細菌訊息傳導機制亦為目前世界上極為熱門的一項研究題材。目前核甘酸的衍生物, 如c-AMP, c-GMP, c-di-GMP, c-di-AMP或ppGpp等都在細菌訊息傳導機制中扮演各種不同的角色. 而其中又以c-di-GMP此一衍生物在細菌的致病性程度扮演最重要的角色. c-di-GMP的產生被發現與細菌的群聚現象有很大的關聯, 而在Xanthomonas campestris中, 群聚現象被發現係由rpf基因群的蛋白組來負責細菌在群聚時的訊息傳導. 其中又以RpfF, RpfC, 及RpfG此三個蛋白扮演最重要的角色. RpfF蛋白被發現負責細菌群聚時所須的訊息分子的合成, RpfC被發現負責此訊息分子的接受, 而RpfG則負責c-di-GMP分子的濃度控制. 基本上, c-di-GMP的濃度大小由兩類蛋白來控制, 一類係含有GGDEF保留胺基酸的c-di-GMP合成酵素, 一類係含有EAL或HD-GYP保留胺基酸的c-di-GMP水解酵素. 而上述的RpfG則為一含有HD-GYP保留胺基酸的c-di-GMP水解酵素. 故Xanthomonas campestris的致病性與此一病菌的群聚效應終於可被聯繫在一起. 有趣的是, 一般病原菌中皆含有為數不少的此二類酵素, 如在Xanthomonas campestris或在Stenotrophomonus maltophilia皆含有二十個以上的此類酵素, 而RpfG蛋白最近亦被發現與其它含有GGDEF保留胺基酸的c-di-GMP合成酵素有很強的作用, 有些可促進其功能, 有些則可抑制其功能. 故此類蛋白之間的作用, 及其與c-di-GMP, c-di-AMP或ppGpp二級訊息傳遞分子之間的作用及功能整合是一個另人非常有興趣的課題. 本實驗室目前將以此類的課題為研究重心, 希望能將大部份所有與此類蛋白有關的複合体結構解析出來, 並以結構的觀點來瞭解細菌的訊息傳導機制. 希冀將來能研發出不致引起細菌抗藥性的新型抗生素. 
下圖為以上說明的一簡圖, 供大家參考. 此一圖形係由下一回顧性論文中取出並加以改進.

實驗室目前亦擬建立一個仿生抗体中心及仿生生物膜中心。由於利用X-ray晶体繞射雖然是一個極為有效的解析生化大分子結構的技術, 但如何得到有用的大分子晶体一直是結構生物學者的一大痛處. 有鑑於此, 目前世界上的趨勢是利用抗体與擬結晶的蛋白或核酸分子結合, 再將此複合体做結晶篩選. 由於抗体分子能將擬結晶的蛋白分子含有較動態的部份固定住, 故一般認為抗体分子將有效的促進不易結晶的蛋白或膜蛋白分子結晶. 但困難的是單株抗体取得很難, 一般都須將抗原注射到動物如牛、羊中, 並須等幾個月後再進行單株抗体的篩選. 所以往往都須花費很大並須等待半年以後才能得到所要的單株抗体. 故此一方式對於結構生物的研究並不容易. 但目前世界上已有一先進的仿生抗体技術, 可輕易的只須利用試管篩選出有效的單株抗体基因, 並可快速的在大腸桿菌中表達出此單株抗体. 在短短幾個星期中, 即可獲得大量的有效單株抗体, 而費用亦可大量減少. 估計此一技術將在此一領域造成革命性的改良. 本實驗室已掌握此一關鍵性技術, 相信配合此一技術, 上述的所有負責細菌訊息傳導機制中有關的蛋白結構將可被順利解出。

另外, 膜蛋白的功能及結構也一直是生命科學領域研究的瓶頸. 此乃因膜蛋白都俱有一段脂溶性的結構, 所以並不溶於水溶液中, 造成它們在水溶液中並無正確功能及無法得到其結構. 但諷刺的是, 膜蛋白卻又在生命科學領域中扮演了關鍵性的角色, 因為每一細胞都須藉著膜蛋白與外界進行物質交換, 以維持其生命狀態. 所以如何有效研究膜蛋白的功能與結晶是世界上所以生命科學研究人員的夢想. 目前有一仿生生物膜的奈米粒子技術可將膜蛋白有效的包裹在其中, 並發現此一系統可達到快速研究膜蛋白分子的功能. 本實驗室目前亦已掌握到此一關鍵性技術, 並擬應用此一技術在細菌訊息傳導中有關信號接受体膜蛋白的功能及結構研究。.

值得一提的是, 本實驗室在過去幾年得到充份的計畫支援(包括教育部第二梯次的大學追求卓越計畫、國科會、農委會、及衛生署等單位), 目前已建立一世界級的結構蛋白体研究中心, 包括各樣與結構生物學研究有關等的貴重儀器, 並配備各樣昂貴的電腦設備, 以快速解析生化分子的三度空間結構。進入本實驗室的同學將可學習到最先進的各式基因轉殖技術, 蛋白表達及純化, X-ray晶体結構決定或核磁共振結構解析等重要技術, 對同學將來的出路, 不管在學術界或產業界等, 都有很大的幫助。實驗室目前有專案助理教授一位,博士後研究二位, 博士班學生六位, 及碩士班學生五位, 同學們皆能互相幫忙, .相處融洽, 順利拿到學位 歡迎對此一跨領域有興趣的同學加入此一微生物結構基因体研究的大家庭。

 

上圖為花椰菜受到植物黑腐病原菌Xanthomonas campestris 產生的染感情形(右圖). 其整個基因体已被解析出(左圖), 吾人可從其中找尋出俱重要功能的基因, 並將其放大, 轉殖至大腸桿菌中大量表達, 以篩選其晶体. 再利用X-ray晶体繞射得到其繞射資料. 由此繞射資料, 吾人將可利用軟体計算出其可能的電子密度圖, 並由此得到此一基因產物可能的三度空間結構圖. 由於蛋白的功能與其結構習習相關, 吾人將可由其結構探討其能的功能並由實驗中再加以驗證!

 

上圖為本實驗室已解析出的一些蛋白的三度空間結構. 由於利用X-ray繞射解析生化大分子的三度空間結構在過去為一極艱難的工作, 但目前由於一些技術上的突破, 此一任務已變為相對容易許多. 本實驗室亦有碩士班學生在二年內即已解析出蛋白結構並發表論文者. 所以雖然同學們在過去可能沒有接觸到此一先進領域, 但是在本實驗室中將可接受到此一領域的訓練並進入此一生物科技中新藥研發最重要的一環!

 

上圖則為Clp蛋白的結構及其與c-di-GMP的結合情形. C-di-GMP為目前所發現在細菌中與其致病性有關最重要的傳遞分子. 其可控制細菌是否要產生致病性因子或以生物保護膜的形式存在. 而c-di-GMP到底如何執行此一重要功能目前尚無具体結論. 本實驗室目前已解析出一類屬於c-AMP接受体的類似蛋白 (Clp), 並發現其不與c-AMP結合, 卻為c-di-GMP的重要受体. 由於c-di-GMP已被發現與細菌的群聚效應及與病菌的致病因子的產生有很大的關聯, 故本實驗室在此一領域的發現相信對未來新型抗生素的研發將有很大的助益. 有興趣者請參閱本實驗室最近發表的論文:
