Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.UniRule annotation

Catalytic activityi

AMP + diphosphate = adenine + 5-phospho-alpha-D-ribose 1-diphosphate.UniRule annotation

Pathwayi: AMP biosynthesis via salvage pathway

This protein is involved in step 1 of the subpathway that synthesizes AMP from adenine.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Adenine phosphoribosyltransferase (apt2)
This subpathway is part of the pathway AMP biosynthesis via salvage pathway, which is itself part of Purine metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes AMP from adenine, the pathway AMP biosynthesis via salvage pathway and in Purine metabolism.

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.
