Saccharomonospora azurea SZMC 14600 is a member of the family Pseudonocardiaceae exclusively used for industrial scale production of primycin a large 36-membered non-polyene macrolide lactone antibiotic belonging to the polyketide class of natural products. Even though maximum antibiotic yield has been achieved by empirically optimized two-step fermentation process, little is known about the molecular components and mechanisms underlying the efficient antibiotic production. In order to identify differentially expressed proteins (DEPs) between the pre- and main-fermentation stages of primycin, comparative 2D-PAGE experiments were performed. In total, 98 DEP spots were reproducibly detected, out of which four spots were excised from gels, and identified through MALDI-TOF/TOF mass spectrometry. Peptide mass fingerprint analysis revealed peptide matches to HicB antitoxin for the HicAB toxin-antitoxin system (EHK86651), to a nucleoside diphosphate kinase regulator ((Ndk; EHK81899) and two other proteins with unknown function (EHK88946 and EHK86777).
