Penicillin-binding proteins of Thiobacillus versutus.
The cytoplasmic membrane of Thiobacillus versutus was found to contain at least nine penicillin-binding proteins (PBPs) with apparent molecular weights as judged by sodium dodecyl sulphate polyacrylamide slab gel electrophoresis of 87000 (PBP1), 81000 (PBP2), 68000 (PBP3), 63000 (PBP4), 57000 (PBP5), 40000 (PBP6), 37000 (PBP70, 33000 (PBP8) and 31000 (PBP9). The PBP pattern of T. versutus was thus quite different from that of the Enterobacteria and the Pseudomonads. Also the properties of the PBPs of T. versutus such as affinity for various beta-lactam antibiotics, heat stability and release of bound penicillin were different from similar properties of Escherichia coli, Pseudomonas aeruginosa and other gram-negative bacteria.
