چکیده انگلیسی
Analysis of the oligomeric state of a protein may provide insights into its physiological functions. Because membrane proteins are considered to be the workhorses of energy generation and polypeptide and nutrient transportation, in this study we characterized the membrane-associated proteome of Streptomyces coelicolor by two-dimensional (2D) blue native/sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), high-resolution clear native/native PAGE, and native/SDS-PAGE. A total of 77 proteins were identified, and 20 proteins belonging to 15 complexes were characterized. Moreover, the resolution of high-resolution clear native/SDS-PAGE is much higher than that of blue native/SDS-PAGE. OBP (SCO5477) and BldKB (SCO5113) were identified as the main protein spots from the membrane fractions of S. coelicolor M145, suggesting that these two proteins are involved in extracellular peptide transportation. These two transporters exhibited multiple oligomeric states in the native PAGE system, which may suggest their multiple physiological functions in the development of S. coelicolor.
