PdxA family (IPR005255)

Short name: PdxA_fam

Family relationships


This entry represents the PdxA family. PdxA is an NAD+-dependent 4-hydroxythreonine 4-phosphate dehydrogenase (EC: active in pyridoxal phosphate biosynthesis [PMID: 12896974]. PdxA2, a functional paralogue of PdxA, catalyzes the NAD-dependent oxidation and subsequent decarboxylation of D-erythronate 4-phosphate to produce dihydroxyacetone phosphate (DHAP). It can also use D-threonate 4-phosphate as substrate [PMID: 27294475, PMID: 27402745]. This family also includes TphB, involved in terephthalate degradation [PMID: 16517628].
