Ligands: CL, DTT, GOL, NA, P6G, SO4 Gene: HMGR (Methanothermococcus thermolithotrophicus ATCC 35097) Activity: Hydroxymethylglutaryl-CoA reductase (NADPH), with EC number 1.1.1.34 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Publication Abstract from PubMed 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) catalyses the last step in mevalonate biosynthesis. HMGR is the target of statin inhibitors that regulate cholesterol concentration in human blood. Here, we report the properties and structures of HMGR from the archaeon Methanothermococcus thermolithotrophicus (mHMGR). The structures of the apoenzyme and the NADPH-complex are highly similar to those of human HMGR. A notable exception is C-terminal helix (Lalpha10-11) that is straight in both mHMGR structures. This helix is kinked and closes the active site in the human enzyme ternary complex, pointing to a substrate-induced structural rearrangement of C-terminal in class-I HMGRs during the catalytic cycle.
