It was confirmed that the key enzyme of coq10 synthesis is p - hydroxybenzoate polyprenyltransferase , encoded by gene ubia in e . coli and lacks specificity to the aggregation length of its substrate ( polyisoprenyl pyrophosphate ) . if gene ubia can be introduced into psb and is high expression in psb , a recombinant strain producing coq10 could be obtained . consequently , the productive cost will decrease sharply 業已證實coq _ ( 10 )生物合成的關鍵酶為對羥基苯甲酸聚異戊二烯焦磷酸轉移酶(在大腸桿菌中該酶由ubia基因編碼) ,該類酶對底物聚異戊二烯焦磷酸( ppp )的聚合長度并無特殊要求。

The good adhesion of zinc coating can be obtained . 3 . pyrophosphate copper electroplating is conducted by ammonium citrate as a auxiliary complexing agent at around 40 , the narrow range of current density can 3 .焦磷酸鹽鍍銅時采用檸檬酸銨作為輔助配合劑,溫度控制在40左右,電流密度范圍較窄,控制在1 . 0a . dm ~ ( - 2 )左右,電鍍時間較長,無法達到無孔狀態,所以必須采用酸性鍍銅加厚銅鍍層。

Histidine a basic amino acid formed only rarely in proteins . it is formed from atp and 5 - phosphoribosyl pyrophosphate in a complex biosynthetic pathway . glutamate is an intermediate in its breakdown 組氨酸:是蛋白質中少有的一種堿性氨基酸。由atp和5 -磷酸核糖基焦磷酸鹽通過復雜的生物合成途徑合成。在其降解過程中可形成谷氨酸。
