Oganomycin GB

Oganomycin GA is Streptomyces str. oganonensis Y-G 19Z and Oganomycin A is produced when p-hydroxycinnamate sodium salt is added to the fermentation medium. Under the action of D-amino acid oxidase, A generates glutaryl derivative, GA; A and GA were converted to B and GB by acid hydrolysis to remove sulfate esters. The effect of B on d-amino acid oxidase was also changed to GB. A and B were more stable than A and B of cemycin, and had stronger effect against Gram-positive and Gram-negative bacteria than Gram-positive bacteria[1].
