Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

5-phosphoribose 1-diphosphate synthase involved in nucleotide, histidine, and tryptophan biosynthesis. Active in heteromultimeric complexes with other 5-phosphoribose 1-diphosphate synthases (PRS2, PRS3, PRS4 and PRS5).2 Publications

Catalytic activityi

ATP + D-ribose 5-phosphate = AMP + 5-phospho-alpha-D-ribose 1-diphosphate.3 Publications

Pathwayi: 5-phospho-alpha-D-ribose 1-diphosphate biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes 5-phospho-alpha-D-ribose 1-diphosphate from D-ribose 5-phosphate (route I).
Proteins known to be involved in this subpathway in this organism are:
  1. Ribose-phosphate pyrophosphokinase 2 (PRS2), Ribose-phosphate pyrophosphokinase 4 (PRS4), Ribose-phosphate pyrophosphokinase 1 (PRS1), Ribose-phosphate pyrophosphokinase 5 (PRS5), Ribose-phosphate pyrophosphokinase 3 (PRS3)
This subpathway is part of the pathway 5-phospho-alpha-D-ribose 1-diphosphate biosynthesis, which is itself part of Metabolic intermediate biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes 5-phospho-alpha-D-ribose 1-diphosphate from D-ribose 5-phosphate (route I), the pathway 5-phospho-alpha-D-ribose 1-diphosphate biosynthesis and in Metabolic intermediate 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.
