Predicted to enable gamma-glutamyl-peptidase activity. Predicted to be involved in several processes, including poly-gamma-glutamate metabolic process; response to ethanol; and tetrahydrofolylpolyglutamate metabolic process. Located in extracellular space. Orthologous to human GGH (gamma-glutamyl hydrolase). [provided by Alliance of Genome Resources, Apr 2022]
