β-Lattamasi

Descrizione:

β-Lattamasi è un enzima che svolge un ruolo cruciale nella resistenza agli antibiotici, in particolare contro gli antibiotici β-lattamici come le penicilline e le cefalosporine. È prodotta da vari batteri, comprese specie Gram-positive e Gram-negative. La funzione principale di β-Lattamasi è idrolizzare l'anello β-lattamico di questi antibiotici, rendendoli inefficaci e consentendo ai batteri di sopravvivere in presenza di questi farmaci. L'enzima presenta una gamma di caratteristiche, inclusa la sua capacità di variare in specificità e attività a seconda del ceppo batterico e del tipo di antibiotico β-lattamico. I β-Lattamasi possono essere classificati in diversi gruppi in base alla loro struttura molecolare e meccanismo d'azione, inclusi β-Lattamasi di serina e metallo-β-Lattamasi. La presenza di geni β-Lattamasi nelle popolazioni batteriche è una preoccupazione significativa negli ambienti clinici, poiché contribuisce al crescente problema della resistenza agli antibiotici, rendendo le infezioni più difficili da trattare. Comprendere i meccanismi e le caratteristiche dei β-Lattamasi è essenziale per sviluppare nuove strategie per combattere le infezioni resistenti agli antibiotici.
