Abstract:
A precursor of biphenomycin A in mixed culture of Streptomyces griseorubiginosus No. 43708 with Pseudomonas maltophilia No. 1928 was isolated and characterized. The structure of the precursor, designated biphenomycin C was determined to be a peptide which is composed of biphenomycin A and arginylserine residue (Fig. 1), on the basis of chemical and spectroscopic evidence.
