On Glumamycin, a New Antibiotic. VI. An Approach to the Amino Acid Sequence

To elucidate the amino acid sequence of glumamycin, glumamycin and DNP-glumamycin have been partially hydrolyzed with hydrochloric acid, and various peptides have been isolated by column chromatography on ionexchange resin or talc-celite, paper chromatography and paper ionophoresis. From the structures of the peptides, two possible structures (A and B) for glumamycin have been presumed.
