Pyridoxine 5'-phosphate synthase

Gene

pdxJ

Organism
Pseudomonas entomophila (strain L48)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the complicated ring closure reaction between the two acyclic compounds 1-deoxy-D-xylulose-5-phosphate (DXP) and 3-amino-2-oxopropyl phosphate (1-amino-acetone-3-phosphate or AAP) to form pyridoxine 5'-phosphate (PNP) and inorganic phosphate.UniRule annotation

Catalytic activityi

1-deoxy-D-xylulose 5-phosphate + 3-amino-2-oxopropyl phosphate = pyridoxine 5'-phosphate + phosphate + 2 H2O.UniRule annotation

Pathwayi: pyridoxine 5'-phosphate biosynthesis

This protein is involved in step 5 of the subpathway that synthesizes pyridoxine 5'-phosphate from D-erythrose 4-phosphate.UniRule annotation
Proteins known to be involved in the 5 steps of the subpathway in this organism are:
  1. D-erythrose-4-phosphate dehydrogenase (epd)
  2. Erythronate-4-phosphate dehydrogenase (pdxB)
  3. Phosphoserine aminotransferase (serC)
  4. 4-hydroxythreonine-4-phosphate dehydrogenase (pdxA)
  5. Pyridoxine 5'-phosphate synthase (pdxJ)
This subpathway is part of the pathway pyridoxine 5'-phosphate biosynthesis, which is itself part of Cofactor biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes pyridoxine 5'-phosphate from D-erythrose 4-phosphate, the pathway pyridoxine 5'-phosphate biosynthesis and in Cofactor biosynthesis.

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.
