Protein

ATPase 3, plasma membrane-type

Gene

AHA3

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

Functioni

The plasma membrane H+ ATPase of plants and fungi generates a proton gradient that drives the active transport of nutrients by H+-symport. The resulting external acidification and/or internal alkinization may mediate growth responses.

Catalytic activityi

ATP + H2O + H+(In) = ADP + phosphate + H+(Out).

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.
