Protein

Beta-lactamase

Gene

blaC

Organism
Mycobacterium bovis (strain ATCC BAA-935 / AF2122/97)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Extended spectrum beta-lactamase (ESBL) that inactivates beta-lactam antibiotics by hydrolyzing the amide group of the beta-lactam ring. Displays high levels of penicillinase and cephalosporinase activity as well as measurable activity with carbapenems, including imipenem and meropenem. Plays a primary role in the intrinsic resistance of mycobacteria to beta-lactam antibiotics.By similarity

Catalytic activityi

A beta-lactam + H2O = a substituted beta-amino acid.By similarity

Enzyme regulationi

Is inhibited by clavulanate.By similarity
