Taxonomic identifier

559292 [NCBI]

Taxonomic lineage

Eukaryota › Fungi › Dikarya › Ascomycota › Saccharomycotina › Saccharomycetes › Saccharomycetales › Saccharomycetaceae › Saccharomyces

Protein attributes

Sequence length	181 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis. May lack catalytic activity.
Catalytic activity	AMP + diphosphate = adenine + 5-phospho-alpha-D-ribose 1-diphosphate. Ref.4
Pathway	Purine metabolism; AMP biosynthesis via salvage pathway; AMP from adenine: step 1/1.
Subcellular location	Cytoplasm.
Miscellaneous	Present with 937 molecules/cell in log phase SD medium. Ref.5
Sequence similarities	Belongs to the purine/pyrimidine phosphoribosyltransferase family.
