Protein

Oxalate--CoA ligase

Gene

AAE3

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

Functioni

Oxalyl-CoA synthetase acting exclusively against oxalate. No activity with malonate, succinate, malate, acetate, formate, lactate, glycolate, glyoxylate or glutarate. Required for oxalate degradation, normal seed development and defense against oxalate-producing fungal pathogens.1 Publication

Catalytic activityi

ATP + oxalate + CoA = AMP + diphosphate + oxalyl-CoA.1 Publication

Kineticsi

  1. KM=149 µM for oxalate1 Publication
  1. Vmax=11.4 µmol/min/mg enzyme1 Publication

pH dependencei

Optimum pH is 8.0.1 Publication

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.
