>TIGR00559 pdxJ pyridoxal phosphate biosynthetic protein PdxJ; InterPro: IPR004569 Pyridoxal phosphate is the active form of vitamin B6 (pyridoxine or pyridoxal). PLP is a versatile catalyst, acting as a coenzyme in a multitude of reactions, including decarboxylation, deamination and transamination , , . PLP-dependent enzymes are primarily involved in the biosynthesis of amino acids and amino acid-derived metabolites, but they are also found in the biosynthetic pathways of amino sugars and in the synthesis or catabolism of neurotransmitters; pyridoxal phosphate can also inhibit DNA polymerases and several steroid receptors . Inadequate levels of pyridoxal phosphate in the brain can cause neurological dysfunction, particularly epilepsy . PLP enzymes exist in their resting state as a Schiff base, the aldehyde group of PLP forming a linkage with the epsilon-amino group of an active site lysine residue on the enzyme. The alpha-amino group of the substrate displaces the lysine epsilon-amino group, in the process forming a new aldimine with the substrate. This aldimine is the common central intermediate for all PLP-catalyzed reactions, enzymatic and non-enzymatic . In Escherichia coli, the pdx genes involved in vitamin B6 have been characterised , , . This entry represents PdxJ, which catalyses the condensation of 1-amino-3-oxo-4-(phosphohydroxy)propan-2-one and 1-deoxy-D-xylulose-5-phosphate to form pyridoxine-5'-phosphate. The product of the PdxJ reaction is then oxidized by PdxH to pyridoxal 5'-phosphate.; GO: 0008615 pyridoxine biosynthetic process, 0005737 cytoplasm.
