The penicillin-binding proteins of Caulobacter crescentus

Journal of Biochemistry

Abstract

The proteins that specifically bind penicillin G were studied with Caulobacter crescentus. This organism possessed at least 5 penicillin-binding proteins (PBPs): PBP 1A (132 K), PBP 1Bs (98 K), PBP 2 (77 K), PBP 3 (64 K), and PBP 4 (50 K). As expected from the unique morphology, the C. crescentus PBPs were different from those of other sources in molecular weight and localization: C. crescentus did not possess PBPs of low molecular weight. PBP 4 was found only in the outer membrane, while the other PBPs were present mostly in the inner membrane.

Bacterial Cell Wall Structure (ASM)

Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids. Here is the latest research on bacterial cell wall structures.
