摘要

Soluble lytic transglycosylase B1 from Pseudomonas aeruginosa was coupled to Sepharose and used to immobilize interaction partners from membrane protein extracts. Penicillin-binding protein 2 (PBP2) was identified as a binding partner, suggesting that the two proteins function together in the biosynthesis of peptidoglycan. By use of an engineered truncated derivative, the N-terminal module of PBP2 was found to confer the binding properties.
