The present invention relates to the base sequence of whole genes involved in the biosynthesis of FR-008 polyketides derived from
Streptomyces
sp. FR-008. This base sequence comprises genes coding for ketosynthase (KS), acyl transferase (AT), acyl carrier protein (ACP), ketoreductase (KR), dehydratase (DH) and enoyl reductase (ER) domains, and genes coding for modifier enzymes, such as ABC transporter, cytochrome P450 monooxygenase, ferredoxin, thioesterase, sugar synthetic protein, FAD-dependent monooxygenase, 4-amino-4-deoxychorismate (ADC) synthase and ADC lyase. The gene base sequence according to the present invention can be used to increase the productivity of the existing FR-008 polyketides or produce new FR-008 polyketides, through modification of its parts.
本发明涉及参与 FR-008 多酮
生物合成的全
基因的碱基序列,这些多酮来自于
链霉菌
sp.FR-008。该碱基序列包括编码酮合成酶(KS)、酰基转移酶(AT)、酰基载体蛋白(ACP)、酮还原酶(KR)、脱
水酶(DH)和烯酰还原酶(ER)结构域的
基因,以及编码
修饰酶的
基因、如 ABC 转运体、细胞色素 P450 单氧化酶、
铁氧还蛋白、
硫酯酶、糖合成蛋白、FAD 依赖性单氧化酶、4-
