Figure 3 (a) A schematic diagram with the numbering scheme of
PLP. (b) Stereoview of the active site of the yeast protein
P007. The cofactor and residues involved in the active site are
shown as a ball-and-stick model along with the C^ trace
of the protein. The cofactor PLP is covalently bound to Lys49
and makes a hydrogen bond with Arg239. The phosphate group
interacts with Ser224 and Thr242. The O3 of the pyridine ring
makes a hydrogen bond to Asp70.
