Comparison of the partial potential active site of L-aminopeptidase and its mutants based on L-aminopeptidase from O. anthropic (PDB code: 1B65). A-C: Stereoview of the potential active site of L-carnosine synthase (WT), G310A, and G310S. The asymmetric unit is colored in green and cyan, separately. The positively and negatively charged regions of molecular surface at residue 310 are colored in blue and red
