Abstract
beta-Lactam antibiotics such as penicillins and cephalosporins have a four-atom ring as a common element in their structure. The beta-lactamases, which catalyze the inactivation of these antibiotics, are of great interest because of their high incidence in pathogenic bacteria. A novel oligomeric class C beta-lactamase (Est-Y29) from a metagenomic library was expressed, purified and crystallized. The recombinant protein was expressed in Escherichia coli with an N-terminal 6xHis tag and purified to homogeneity. EstY-29 was crystallized and X-ray intensity data were collected to 1.49 A resolution using synchrotron radiation.
