摘要: 采用刺激实验法确定红曲色素的合成前体。考察了不同氨基酸和短链脂肪酸等对色素合成的影响,结果表明缬氨酸、异亮氨酸、蛋氨酸、谷氨酸以及乙酸、丙酸等具有前体的作用,能够刺激色素的生产。而且它们都具有转化为聚酮合成前体的共同特征。所以聚酮途径被认为是红曲色素合成的主要途径。

Abstract: Feed stimulating experiments were used to confirm precursors of monascus pigments. Different amino acids and branched fatty acids effects on monascus pigments production were investigated. The results showed that the amino acids and branched fatty acids, such as valine, isoleucine, methionine, glutamine, acetate, propionate can act as precursors and stimulate pigments biosynthesis. Besides, these compounds have the same character that all can be transformed to precursors of polyketide biosynthesis. So the polyketide pathway is presumed to be the main biosynthetic pathway of antibiotic monascus pigments.

Key words: monascus pigments, polyketide, biosynthesis
