| Name | decarboxylation/antiport proton-motive cycle: aspartate-alanine |
| Type | SYSTEM |
| Description | This Genome Property represents a proton-motive cycle. A cycle of decarboxylating an aspartate to alanine plus CO2, then exchanging the cytosolic alanine for an extracellular asparate, has the net effect of consuming one proton. Analogous systems for antiport of substrates related by decarboxylation include, for example, the pairing of an acid-induced arginine decarboxylase with an arginine-agmatine antiporter as in Escherichia coli. |
