Fig. 3From: Characterization of a new L-carnosine synthase mined from deep-sea sediment metagenomeSubstrate binding pocket of aminopeptidase generated by homology modeling and molecular docking. The 3D structure of L-aminopeptidase is shown in the mode of Cartoon with subunits given in different colors (green and yellow). The substrate is illustrated in sticks. Residues whose atoms are within 3 Å of the substrate are in linesBack to article page
