Accession	GenProp0875
Name	decarboxylation/antiport proton-motive cycle: tyrosine-tyramine
Type	SYSTEM
Description	The decarboxylation of tyrosine to tyramine consumes a proton. Exchange of tyrosine for tyramine by an antiporter completes a cycle that effectively removes a cytosolic proton. Decarboxylation/antiporter systems for this and other (e.g. aspartate-alanine) substrate pairs can provide protection against acidic pH.
Parent Property	GenProp0873: ion-motive antiporter cycles GenProp0874: response to acid (low pH) environment
