Figure 1. Final electron density maps in the region of the
S[1] substrate pocket and active site of SGPB (or in the
vicinity of the reduced peptide bond for
OMTKY3-Q[CH[2]NH[2]^+]-Asp19I), superimposed onto the final
refined models. Map coefficients are 2|F[o]| - |F[c]| contoured
at 1s (purple) and |F[o]| - |F[c]| contoured at 2.5s (green) and
at -2.5s (red). Carbon atoms have been coloured yellow, nitrogen
atoms blue and oxygen atoms red. (a) SGPB:OMTKY3-Pro18I; (b)
SGPB:OMTKY3-Q[COO]-Leu18I; (c) OMTKY3-Q[CH[2]NH[2]^+]-Asp19I.
This Figure was made with XtalView[42].
