Control of antibiotic production: Two signaling molecules—SRB1 and SRB2—that induce production of lankacidin and lankamycin in Streptomyces rochei 7434AN4 were isolated and their structures were determined. Each contains a 2,3‐disubstituted γ‐hydroxybutenolide skeleton, and the stereochemistry at C‐1′ is crucial for inducing activity.
抗生素生产的控制:分离出两个诱导罗氏链霉菌7434AN4中兰卡霉素和兰卡霉素产生的信号分子SRB1和SRB2,并确定了它们的结构。每个都包含一个2,3-二取代的γ-羟基丁烯内酯骨架,C-1'处的立体化学对于诱导活性至关重要。
