THE STUDY ON DIFFERENCE OF PROTEIN EXPRESSIONS IN AN ANTIBIOTIC AGPM FERMENTATION PROCESS / 微生物学通报

A new strain of Streptomyces regensis was isolated from soil to produce a novel antibiotic AGPM possessing a strong antitumor activity In order to study on the metabolic path of the novel antibiotic AGPM, the protein patterns from the strain of Streptomyces regensis at different culture period were analyzed by using two eimensional polyacrylamide gel electrophoresis Comparing with sample from growth phase, seventeen new protein spots were found in that from antibiotic production phase The results demonstrated that the special proteins might be related with the antibiotic AGPM biosynthesis from Streptomyces regensis
