※ 引述《mason.bbs@l19.lib.nctu.edu.tw (THE RED DAY~N THE SUN RISER~!)》之銘言： 想知道此結構會造成毒性的意義, 尤其是polycyclic aromatic cpd 為什麼會有毒甚至致癌呢? 謝謝解答 明天要考試剛好有讀到 XD 課本舉的一個polycyclic aromatic compound的例子 如 Benzo pyrene 其環狀的結構 容易被人體肝臟的 cytochrome P450 轉變成 Epoxide group (兩個碳一個氧形成的三角環結構) 轉變成Epoxide結構中的兩個碳會變得相當親電性 (electrophilic) 進而去攻擊DNA的含氮鹼基結構 變成 DNA-carcinogen complex 而最後會造成DNA複製時的突變 -

※ 引述《yffurdyeknom (Unhurried Justice)》之銘言： : ※ 引述《tonylaio (包子王子)》之銘言： : 請問大大這是我寫考古題碰到的問題 : 請問某一個酵素的active site 中有一個glutamic acid 相當重要可以參與反應 : a.此Glu可能具有什麼功能 : 我想可能是R group上的carbonyl group在酵素中提供一個electrophilic site，而 : 這跟酵素可進行的反應就大有關係(可以固定住多電子的反應物或和nucleophile進行 : 初步反應)。 補充一下 Glu也可能利用cabonyl group和cofactor形成離子鍵(ex:Mg) 利用cofactor穩定substrate催化反應 : b.將Glu更換為proline對此酵素結構活性可能有什麼影響
