FIG. 3

A, Cα superimposition of the E. coli shikimate dehydrogenases AroE (green) and YdiB (yellow) with HI0607 (gray), indicating a conserved three-dimensional structure for proteins in the shikimate dehydrogenase family. B, superimposition of active site residues from E. coli AroE (green) and YdiB (yellow) with HI0607 (gray). Residue numbering is according to the HI0607 sequence with single letter amino acid abbreviations. Lys-67, Asp-103, Asn-88, Asn-101, Thr-89, and Gln-242 are conserved in all dehydrogenases, indicating a role in either catalysis or substrate binding.
