Method: X-ray diffraction, Resolution 1.94Å Ligands: CD, IMP Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function Q99QC1_KLEAE This protein is a serine beta-lactamase with a substrate specificity for cephalosporins.[ARBA:ARBA00003808] Publication Abstract from PubMed Nucleotides were effective in inhibiting the class C beta-lactamase CMY-10. IMP was the most potent competitive inhibitor, with a Ki value of 16.2 muM. The crystal structure of CMY-10 complexed with GMP or IMP revealed that nucleotides fit into the R2 subsite of the active site with a unique vertical binding mode where the phosphate group at one terminus is deeply bound in the subsite and the base at the other terminus faces the solvent.
