In enzymology, a 2-oxopropyl-CoM reductase (carboxylating) (EC 1.8.1.5) is an enzyme that catalyzes the chemical reaction
2-mercaptoethanesulfonate + acetoacetate + NADP+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.
Structural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 2C3C and 2C3D.
