Figure 2. Peptide deformylase in complex with the reaction product Met-Ala-Ser. a, Peptide binding scheme; Gly 45, Glu 88, Gly 89, His 132 and Glu 133 are conserved residues. Dashed lines indicate hydrogen bonds. Mean distances between donor and acceptor atoms as observed in the three crystallographically independent monomers are given in Å . The distance between the N-terminal amino group of the peptide to the Ni^2+-ion is 3.9 Å. b, Protein atoms (white, carbon; red, oxygen; dark blue, nitrogen; green, sulphur) and catalytic metal (magenta, Ni^2+) are depicted as space-filling spheres. Met-Ala-Ser is in ball-and-stick representation with carbon atoms and bonds colored yellow. Water molecules W1, W2 are shown as small light blue spheres.
