2-oxopropyl-CoM reductase (carboxylating)

In enzymology, a 2-oxopropyl-CoM reductase (carboxylating) (EC number|1.8.1.5) is an enzyme that catalyzes the chemical reaction

:2-mercaptoethanesulfonate + acetoacetate + NADP⁺ $ightleftharpoons$ 2-(2-oxopropylthio)ethanesulfonate + CO₂ + NADPH

The 3 substrates of this enzyme are 2-mercaptoethanesulfonate, acetoacetate, and NADP⁺, whereas its 3 products are 2-(2-oxopropylthio)ethanesulfonate, CO₂, and NADPH.

This enzyme belongs to the family of oxidoreductases, specifically those acting on a sulfur group of donors with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 2-mercaptoethanesulfonate,acetoacetate:NADP+ oxidoreductase (decarboxylating). Other names in common use include NADPH:2-(2-ketopropylthio)ethanesulfonate, oxidoreductase/carboxylase, and NADPH:2-ketopropyl-coenzyme M oxidoreductase/carboxylase.

tructural studies

As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes PDB link|2C3C and PDB link|2C3D.
