>cd04879 ACT_3PGDH-like ACT_3PGDH-like CD includes the C-terminal ACT (regulatory) domain of D-3-phosphoglycerate dehydrogenase (3PGDH). ACT_3PGDH-like: The ACT_3PGDH-like CD includes the C-terminal ACT (regulatory) domain of D-3-phosphoglycerate dehydrogenase (3PGDH), with or without an extended C-terminal (xct) region found in various bacteria, archaea, fungi, and plants. 3PGDH is an enzyme that belongs to the D-isomer specific, 2-hydroxyacid dehydrogenase family and catalyzes the oxidation of D-3-phosphoglycerate to 3- phosphohydroxypyruvate, which is the first step in the biosynthesis of L-serine, using NAD+ as the oxidizing agent. In bacteria, 3PGDH is feedback controlled by the end product L-serine in an allosteric manner. In the Escherichia coli homotetrameric enzyme, the interface at adjacent ACT (regulatory) domains couples to create an extended beta-sheet. Each regulatory interface forms two serine-binding sites. The mechanism by which serine transmits inhibition to the active
