Figure 2. Surface representation of the SplC molecule. The catalytic triad (yellow) is blocked by Gly175–Gly176 and the whole Tyr174–Tyr184 loop region interferes with enzymatic activity. The specificity region built by Val119, Phe149, Ile153 and Val173 enables binding of a medium-sized hydrophobic residue.
