    Protein Summary

    389964 encodes a putative beta-lactamase. Structurally, it is similar to proteins in the beta-Lactamase/D-ala carboxypeptidase family from SCOP. It has sequence similarity to COG2367: Beta-lactamase Class A (CD-search E-value: 2e-14 and ffas score: -71.800).  It is expressed as a gene truncation of residues 33-313. Additionally, residues 34-58 and 313 are disordered and not visible in the final model (Fig 1). Both the fold and active site residues of 389964 are conserved when compared with other beta-lactamases.

    Figure 1. 389964 forms a monomer. The N-term is blue and the C-term is red
