Protein

Bifunctional ribose 1,5-bisphosphokinase-thymidine phosphorylase

Gene

phnN

Organism
Roseobacter denitrificans (strain ATCC 33942 / OCh 114) (Erythrobacter sp. (strain OCh 114)) (Roseobacter denitrificans)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the phosphorylation of ribose 1,5-bisphosphate to 5-phospho-D-ribosyl alpha-1-diphosphate (PRPP).By similarity

Catalytic activityi

ATP + alpha-D-ribose 1,5-bisphosphate = ADP + 5-phospho-alpha-D-ribose 1-diphosphate.
Thymidine + phosphate = thymine + 2-deoxy-alpha-D-ribose 1-phosphate.

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), Bifunctional ribose 1,5-bisphosphokinase-thymidine phosphorylase (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.

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.
