Webdermatopatias alérgicas, parasitárias, fúngicas, disturbios endócrinos, dermatopatia alérgica, demodex, leishmaniose 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, cephalosporins, cephamycins, monobactams and carbapenems (ertapenem), although carbapenems are relatively resistant to beta-lactamase. … See more The structure of a Streptomyces serine β-lactamase (SBLs) is given by 1BSG. The alpha-beta fold (InterPro: IPR012338) resembles that of a DD-transpeptidase, from which the enzyme is thought to have evolved from. β … See more The two types of beta-lactamases work on the basis of the two basic mechanisms of opening the β-lactam ring. The SBLs are similar in structure and mechanistically to the β-lactam target penicillin-binding proteins (PBPs) which are necessary for … See more Among Gram-negative bacteria, the emergence of resistance to extended-spectrum cephalosporins has been a major concern. It appeared initially in a limited number of … See more In 1957, amid concern about allergic reactions to penicillin-containing antibiotics, a beta-lactamase was sold as an antidote under … See more Penicillinase is a specific type of β-lactamase, showing specificity for penicillins, again by hydrolysing the β-lactam ring.
