BlaR1 peptidase M56; Production of beta-Lactamase and penicillin-binding protein 2a (which mediate staphylococcal resistance to beta-lactam antibiotics) is regulated by a signal-transducing integral membrane protein and a transcriptional repressor. The signal transducer is a fusion protein with penicillin-binding and zinc metalloprotease domains. The signal for protein expression is transmitted by site-specific proteolytic cleavage of both the transducer, which auto-activates, and the repressor, which is inactivated, unblocking gene transcription. homologs to this peptidase domain, which corresponds to Merops family M56, are also found in a number of other bacterial genome sequences.

84-266 1.08e-39

Peptidase M56-like including those in BlaR1 and MecR1, integral membrane metallopeptidase; This family contains peptidase M56, which includes zinc metalloprotease domain in MecR1 as well as BlaR1. MecR1 is a transmembrane beta-lactam sensor/signal transducer protein that regulates the expression of an altered penicillin-binding protein PBP2a, which resists inactivation by beta-lactam antibiotics, in methicillin-resistant Staphylococcus aureus (MRSA). BlaR1 regulates the inducible expression of a class A beta-lactamase that hydrolytically destroys certain ?-lactam antibiotics in MRSA. Both, MecR1 and BlaR1, are transmembrane proteins that consist of four transmembrane helices, a cytoplasmic zinc protease domain, and the soluble C-terminal extracellular sensor domain, and are highly similar in sequence and function. The signal for protein expression is transmitted by site-specific proteolytic cleavage of both the transducer, which auto-activates, and the repressor, which is inactivated, unblocking gene transcription. All members contain the zinc metalloprotease motif (HEXXH). Homologs of this peptidase domain are also found in a number of other bacterial genome sequences, most of which are as yet uncharacterized.
