Kirromycin is an antibiotic originally isolated from Streptomyces and an inhibitor of protein biosynthesis. It inhibits isoleucine incorporation, polyphenylalanine synthesis, and growth of B. brevis. Kirromycin inhibits elongation factor Tu-dependent peptidyl transfer activity in E. coli.
Methylmalonyl coenzyme A (Methylmalonyl-CoA) 是单链脂肪酸、胆固醇以及某些氨基酸(例如缬氨酸、异亮氨酸、蛋氨酸、苏氨酸)分解后的产物。通过甲基丙二酸单酰辅酶 A 变位酶 (MCM) 和其辅酶维生素 B12,Methylmalonyl coenzyme A 可以被催化转化为琥珀酰辅酶 A。
