Structure of the plasmid-mediated class C beta-lactamase ACT-1.

Akiko Shimizu-Ibuka1, Cédric Bauvois, Hiroshi Sakai, Moreno Galleni.   

Abstract

The crystallographic structure of ACT-1, which is the first plasmid-mediated AmpC-type beta-lactamase to have been completely analyzed in terms of nucleotide sequence and which has a high degree of sequence similarity to the chromosomal AmpC enzymes of Enterobacter cloacae and the plasmid-encoded MIR-1, has been solved at 2.4 A resolution. The overall structure of ACT-1 is similar to those of other class C beta-lactamases, such as the AmpC enzymes from E. cloacae P99 and Escherichia coli.
