In this operon, gadC is glutamate-gamma-aminobutyrate antiporter and gadB is glutamate decarboxylase. They are both involved in intracellular pH regulation and co-expressed in the same operon under the control of Pgad. The gene before Pgad, named gadR, which is constitutively expressed under the control of PgadR, is a positive regulator of Pgad coupled genes while intracellular chloride is level elevated.

Pgad - Intracellular Chloride-Sensing Cassette

Pgad is chloride-sensitive promoter which was first discovered in Lactococcus lactis1, which is a gram-positive bacterium which can live in acidic environment. In this operon, gadC is glutamate-gamma-aminobutyrate antiporter and gadB is glutamate decarboxylase. They are both involved in intracellular pH regulation and co-expressed in the same operon under the control of Pgad. The gene before Pgad, named gadR, which is constitutively expressed under the control of PgadR, is a positive regulator of Pgad coupled genes while intracellular chloride is level elevated.
