Protein
Probable pyridoxal 5'-phosphate synthase subunit SNO3
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
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 a SNZ isoform.
Similarity
Belongs to the glutaminase PdxT/SNO family.
