Reaction

Reaction Comment Organism Reaction ID
shikimate + NADP+ = 3-dehydroshikimate + NADPH + H+ the active enzyme for dehydrogenation of shikimate contains a deprotonated K70 residue, a deprotonated D106, and a protonated Y216. The hydride transfer and the deprotonation of the 3-hydroxyl group of shikimate proceed in a concerted manner. K70 functions as a general base and becomes protonated in the dehydrogenation reaction. The proton is then transferred to the bulk solvent via the short proton-conducting wire. D106 plays a critical role in the transfer of the proton to the bulk solvent Aquifex aeolicus
