• 용도

  Berninamycin A is an antibiotic discovered in 1976 from a strain of Streptomyces. Berninamycin A is a macrocyclic "peptide" comprising atypical amino acids linked to thiazole and oxazoles. Chemically very complex, berninamycin A is an inducer of tipA, a gene that controls the bacterial transcription regulators, TipAL and TipAS, that are central to multidrug resistance. Berninamycin A is closely related to siomycin, a recently discovered inhibitor of oncogenic transcription factor, FoxM1.

• 효소 저해제

  This fungal antibiotic (FW = 1146.12 g/mol; CAS 58798-97-3; Soluble in DMSO), also known as Antibiotic U27810, from Streptomyces bernensis inhibits protein biosynthesis by binding to a complex formed by ribosomal 23S and the L11 protein, thereby disrupting the function of the ribosome’s A site and inhibiting protein synthesis in Gram-positive bacteria. In this respect, it has the same mode of action as thiostrepton. Streptomyces bernensis and Streptomyces azureus, which produce berninamycin and thiostrepton, respectively, possess similar ribosomal RNA methylases that mediate specific pentose-directed methylation of 23S ribosomal RNA, rendering the modified ribosomes resistant to these antibiotics.
