Comments
Although this enzyme binds calcium ions, it is not involved in catalysis.
This enzyme belongs to the short-chain dehydrogenase/reductase (SDR) superfamily, along with Drosophia alcohol dehydrogenase (S00319 in EzCatDB). This enzyme has got a catalytic triad composed of conserved residues, Ser, Tyr, and Lys. The conformation of these residues seems to be similar to that of the homologous enzymes. Thus, the catalytic site seems to catalyze the following reaction.
(A) Hydride transfer from NADPH to keto-substrate (Reduction):
