Figure 2
Electron densities around the active site for the different complexes. The electron densities are maximum-likelihood-weighted 2Fobs − Fcalc maps contoured at the 1σ level; electron densities are highlighted in brown for the substrates and in green for the protein. (a) Native active site showing the modified serine, (b) ferulic acid complex, (c) methyl sinapinate complex, (d) methyl syringate complex, (e) methyl vanillate complex. The figure was prepared using BOBSCRIPT (Esnouf, 1999). |
