Ribose 1,5-bisphosphate phosphokinase PhnN

Gene

phnN

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the phosphorylation of ribose 1,5-bisphosphate to 5-phospho-D-ribosyl alpha-1-diphosphate (PRPP). Accepts ATP but not GTP as a phosphoryl donor, and uses ribose 1,5-bisphosphate but not ribose, ribose 1-phosphate, or ribose 5-phosphate as a phosphoryl acceptor.2 Publications

Catalytic activityi

ATP + alpha-D-ribose 1,5-bisphosphate = ADP + 5-phospho-alpha-D-ribose 1-diphosphate.1 Publication

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

This protein is involved in step 3 of the subpathway that synthesizes 5-phospho-alpha-D-ribose 1-diphosphate from D-ribose 5-phosphate (route II).
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Phosphopentomutase (deoB)
  2. no protein annotated in this organism
  3. Ribose 1,5-bisphosphate phosphokinase PhnN (phnN)
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 II), the pathway 5-phospho-alpha-D-ribose 1-diphosphate biosynthesis and in Metabolic intermediate biosynthesis.

Similar proteinsi

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.
