Gene

ASE1

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at transcript leveli

Functioni

Catalyzes the first committed step of 'de novo' purine biosynthesis from glutamine. Involved in plastid biogenesis and cell division.1 Publication

Catalytic activityi

5-phospho-beta-D-ribosylamine + diphosphate + L-glutamate = L-glutamine + 5-phospho-alpha-D-ribose 1-diphosphate + H2O.

Cofactori

Protein has several cofactor binding sites:
  • [4Fe-4S] clusterBy similarityNote: Binds 1 [4Fe-4S] cluster per subunit.By similarity
  • Mg2+By similarityNote: Binds 1 Mg2+ ion per subunit.By similarity

Pathwayi: IMP biosynthesis via de novo pathway

This protein is involved in step 1 of the subpathway that synthesizes N(1)-(5-phospho-D-ribosyl)glycinamide from 5-phospho-alpha-D-ribose 1-diphosphate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Amidophosphoribosyltransferase 2, chloroplastic (ASE2), Amidophosphoribosyltransferase (AXX17_At4g39730), Amidophosphoribosyltransferase 1, chloroplastic (ASE1), Amidophosphoribosyltransferase 3, chloroplastic (ASE3), Amidophosphoribosyltransferase (AXX17_At4g44210)
  2. Phosphoribosylamine--glycine ligase, chloroplastic (PUR2)
This subpathway is part of the pathway IMP biosynthesis via de novo 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 N(1)-(5-phospho-D-ribosyl)glycinamide from 5-phospho-alpha-D-ribose 1-diphosphate, the pathway IMP biosynthesis via de novo pathway and in Purine metabolism.

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.
