| There are two distinct classes of HMGRs, class I, which is only found in eukaryotes and are membrane bound and class II, which is found in prokaryotes and are soluble. <ref>PMID:11349148</ref> HMGR contains 8 transmembrane domains that have yet to be successfully crystallized, which anchor the protein to the membrane of the endoplasmic reticulum. <ref name="Roitelman"/> The catalytic portion of human HMGR forms a tetramer, with the individual monomers winding around each other. <ref name="Roitelman">PMID:1374417</ref> Within the tetramer, the monomers are arranged into <scene name='HMG-CoA_Reductase/1dq8_2_dimers/3'>two dimers</scene>, each of which contains <scene name='HMG-CoA_Reductase/1dq8_2_active_sites/2'>two active sites </scene>which are formed by residues form both monomers. Each monomer contains <scene name='HMG-CoA_Reductase/1dq8_star3_domains/2'>three domains </scene>, the <scene name='HMG-CoA_Reductase/1dq8_n_domain/2'>N-domain</scene>, the <scene name='HMG-CoA_Reductase/1dq8_l_domain/1'>L-Domain</scene>, and the <scene name='HMG-CoA_Reductase/1dq8_s_domain/1'>S-Domain</scene>. The L-domain is unique to HMGRs while the S-domain, which forms the binding site for NADP, resembles that of [[ferredoxin]]. The S and L domains are connected by a <scene name='HMG-CoA_Reductase/1dq8_cis_loop/6'>“cis-loop”</scene> which is essential for the HMG-binding site. <ref name="Roitelman"/> Salt bridges between residues R641 and E782 as well as <scene name='HMG-CoA_Reductase/1dq8_cis_loop/4'>hydrogen bonds</scene> between E700 and E700 on neighboring monomers compliment the largely hydrophobic dimer-dimer interface. <ref name="Roitelman"/>
