Beta-lactamases are a family of enzymes involved in bacterial resistance to beta-lactam antibiotics. A new biosynthetic enzyme". This is done not only for dosing convenience, but also to minimize resistance development that might occur as a result of varying exposure to one or the other drug. Notable examples of this mode of resistance include methicillin -resistant Staphylococcus aureus MRSA and penicillin-resistant Streptococcus pneumoniae. Unlike the case of beta-lactam antibiotics, the inhibitors act as suicide substrates tazobactam and sulbactam which ultimately leads to the degradation of the beta-lactamase .

We thank Romeo Hizon, Sarah Christianson, and Rebekah Hiebert for technical support. Beta-lactamases are a family of enzymes involved in bacterial resistance to beta- lactam antibiotics.
They act by breaking the beta-lactam ring that allows. Beta-lactamases are enzymes (EC ) produced by bacteria that provide multi-resistance to β-lactam antibiotics such as penicillins, cephalosporins.

Competitive inhibition Uncompetitive inhibition Non-competitive inhibition Suicide inhibition Mixed inhibition. Unlike the case of beta-lactam antibiotics, the inhibitors act as suicide substrates tazobactam and sulbactam which ultimately leads to the degradation of the beta-lactamase . As with the penams, the variety of cephalosporins and cephamycins come from different transamidations, as is the case for the penicillins.

Strategies for combating this form of resistance have included the development of new beta-lactam antibiotics that are more resistant to cleavage and the development of the class of enzyme inhibitors called beta-lactamase inhibitors.

|Like beta-lactam antibiotics, they are processed by beta-lactamases to form an initial covalent intermediate.
