Both forms of the chromosome-encoded β-lactamase of Citrobacter diversus react with β-iodopenicillanate at a rate characteristic of of class A β-lactamases. The active site of form I was labelled with the same reagent. The sequence of the peptide obtained after trypsin hydrolysis is identical with that of a peptide obtained in a similar manner from the chromosome-encoded β-lactamase of Klebsiella pneumoniae.

Abstract
Both forms of the chromosome-encoded β-lactamase of Citrobacter diversus react with β-iodopenicillanate at a rate characteristic of of class A β-lactamases. The active site of form I was labelled with the same reagent. The sequence of the peptide obtained after trypsin hydrolysis is identical with that of a peptide obtained in a similar manner from the chromosome-encoded β-lactamase of Klebsiella pneumoniae.File in questo prodotto:
