- Beta-
lactamases (β-
lactamases) are
enzymes (EC 3.5.2.6)
produced by
bacteria that
provide multi-resistance to beta-lactam
antibiotics such as penicillins...
- beta-
lactamases. Most beta-
lactamases identified in Bacteroides, Prevotella, and
Capnocytophaga belong to the
Ambler class A.
Several beta-
lactamases encoded...
-
class A, C and some
class D beta-
lactamases (avibactam). Like beta-lactam antibiotics, they are
processed by beta-
lactamases to form an
initial covalent intermediate...
- extended-spectrum β-
lactamases but may be more
susceptible to
hydrolysis by metallo-β-
lactamases produced by bacteria. β-

Penicillinase is now
classified as
member of

These β-
