penicillinases

Example:Penicillin-sparing enzymes are preferred in the development of new therapeutic strategies for bacterial infections.

Definition:Enzymes that do not affect the structure of penicillin and thus do not contribute to antibiotic resistance.

Example:Penicillin-conserving enzymes are less common and are typically found in resistant bacteria that have not yet developed complete breakdown mechanisms.

Definition:Enzymes that preserve the structure of penicillin and maintain its effectiveness against bacterial pathogens.
