Figure 1. Stereo representation of the 2F[o] -F[c] electron densities around the active site of one monomer (chain B) of 1510-N. The densities are contoured at 1.0s. Each residue is shown as a stick model (C atom, yellow; N atom, blue; O atom, red; S atom, orange), and a catalytic residue Ser97 is shown in magenta stick.
