PdxA is an NAD+-dependent 4-hydroxythreonine 4-phosphate dehydrogenase active in pyridoxal phosphate biosynthesis.This family consists of putative 4-hydroxy-L-threonine phosphate dehydrogenases from Epsilonproteobacteria. PdxA from Campylobacter jejuni has been shown to play an important role in the PLP (vitamin B6, pyridoxal-5'-phosphate) dependent regulation of flagellar motility, thereby altering host colonization.
