>cd00644 HMG-CoA_reductase_classII Class II hydroxymethylglutaryl-coenzyme A (HMG-CoA) reductase (HMGR). Hydroxymethylglutaryl-coenzyme A (HMG-CoA) reductase (HMGR), class II, prokaryotic enzyme is a homodimer. Class II enzymes are found primarily in prokaryotes and Archaeoglobus fulgidus and are soluble as they lack the membrane region. Enzymes catalyze the synthesis of coenzyme A and mevalonate in isoprenoid synthesis. Bacteria, such as Pseudomonas mevalonii, which rely solely on mevalonate for their carbon source, catalyze the reverse reaction, using an NAD-dependent HMGR to deacetylate mevalonate into 3-hydroxy-3-methylglutaryl-CoA. Human and bacterial HMGR differ in their active site architecture.
