The HMG binding pocket is the site of catalysis in HMGR. <scene name='HMG-CoA_Reductase/1dqa_cis_loop2/2'> The “cis-loop” that bends over the top of HMG </scene> is a critical structural element of this binding site. Residues <scene name='HMG-CoA_Reductase/1dqa_e_and_d/2'>E559 and D767</scene> and are positioned in the active site as is <scene name='HMG-CoA_Reductase/1dqa_k691/2'>K691 which is only 2.7 angstroms from the HMG O2 carbonyl oxygen</scene>. It is this K691 that likely stabilizes the negatively charged oxygen of the first mevaldyl-CoA intermediate. The mevaldyl CoA intermediate is subsequently converted to Mavaldehyde with added stabilization from <scene name='HMG-CoA_Reductase/1dqa_h866/2'>H866, which is within hydrogen bonding distance of the thiol group</scene>.  It is then believed that the close proximity of <scene name='HMG-CoA_Reductase/1dqa_e_and_d/2'>E559 and D767</scene> increases the pKA of E559, allowing it to be a proton donor for the reduction of mevaldehyde into mevalonate.<br />

====Tip #3: When Transitioning focus to a new domain, it is best to zoom out and orient the reader to the new domain of interest====
