The FAD-Domain exists in each monomer subunit of GlpD and is embedded into the phospholipid membrane bilayer. Substrate binding occurs at this domain which causes a conformational change to the structure of the GlpD enzyme. The base of the enzyme has positivly charged regions capable of association with the negatively charged heads of the phospholipid membrane. <ref>PubMed:18296637</ref2> |

Glycerol 3-Phosphate Dehydrogenase
Introduction
Glycerol 3-Phosphate Dehydrogenase (GlpD) is an oxidoreductase enzyme which catalyzes the reaction of transfer of electrons between molecules. GlpD is a membrane associated enzyme that is involved in glycerol metabolism, ubiquinone, glyceroneogenesis and respiratrion in E. coli. In Ecoli, many newly discovered structures of GlpD are being used to aid in transfer of electrons into the respiratory pathway and also for the metabolism of glycerol into its precursors for other pathways. The GlpD enzyme contains a flavin adenine dinucleotide (FAD active site which plays a major role in the respiratory electron transport chain and in synthesis of cellular components. [1]
