>cd04902 ACT_3PGDH-xct C-terminal ACT (regulatory) domain of D-3-phosphoglycerate dehydrogenase (3PGDH). The C-terminal ACT (regulatory) domain of D-3-phosphoglycerate dehydrogenase (3PGDH), with an extended C-terminal (xct) region from 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. Some 3PGDH enzymes have an additional domain formed by an extended C-terminal region. This additional domain introduces significant asymmetry to the homotetramer. Adjacent ACT (regulatory) domains interact, creating two serine-binding sites, however, this asymmetric arrangement results in the formation of two different and distinct domain interfaces between iden
