In enzymology, hydroxymethylglutaryl-CoA reductase (EC 1.1.1.88) is an enzyme that catalyzes the chemical reaction

 
 
 
2 H+
Hydroxymethylglutaryl-CoA reductase
 
2 H+
 
+ 2 NADH
 

The substrates of this enzyme are mevalonic acid, coenzyme A, and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA), reduced NADH, and two protons. [1]

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is (R)-mevalonate:NAD+ oxidoreductase (CoA-acylating). [2] Other names in common use include beta-hydroxy-beta-methylglutaryl coenzyme A reductase, beta-hydroxy-beta-methylglutaryl CoA-reductase, 3-hydroxy-3-methylglutaryl coenzyme A reductase, and hydroxymethylglutaryl coenzyme A reductase.
