Protein

Pyridoxal 5'-phosphate synthase subunit PdxT

Gene

pdxT

Organism
Mycobacterium tuberculosis (strain CDC 1551 / Oshkosh)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the biosynthesis of pyridoxal 5'-phosphate. The resulting ammonia molecule is channeled to the active site of PdxS.UniRule annotation

Catalytic activityi

D-ribose 5-phosphate + D-glyceraldehyde 3-phosphate + L-glutamine = pyridoxal 5'-phosphate + L-glutamate + 3 H2O + phosphate.UniRule annotation
L-glutamine + H2O = L-glutamate + NH3.UniRule annotation

Pathwayi: pyridoxal 5'-phosphate biosynthesis

This protein is involved in the pathway pyridoxal 5'-phosphate biosynthesis, which is part of Cofactor biosynthesis.UniRule annotation
