vitro assays of enzymes involved in the biosynthesis of maleidrides from polyketides in fungi were performed. The results show that the enzymes are closely related to primary metabolism enzymes of the citric acid cycle in terms of stereochemical preferences, but with an expanded substrate selectivity. A key citrate synthase can react both saturated and unsaturated acyl CoA substrates to give solely
对真菌中的聚酮化合物生物合成马来酰亚胺所涉及的酶进行了体外测定。结果表明,这些酶在立体化学偏好方面与柠檬酸循环的初级代谢酶密切相关,但具有扩大的底物选择性。一种关键的柠檬酸合酶可以与饱和和不饱和的酰基辅酶 A 底物反应,仅产生抗取代的柠檬酸。这经历抗脱水以提供不饱和前体,该前体在体外通过类酮类异构酶酶环化以产生比索草酸。
