Accession | GenProp0872 | |
Name | decarboxylation/antiport proton-motive cycle: histidine-histamine | |
Type | SYSTEM | |
Description | The decarboxylation of histidine to histamine consumes a proton. Exchange of histamine for histadine 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. | |
