Protein

Pyridoxal 5'-phosphate synthase subunit PdxT

Gene

pdxT

Organism
Staphylococcus carnosus (strain TM300)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-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

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
