Predicted to enable glutathione transferase activity; maleylacetoacetate isomerase activity; and protein homodimerization activity. Predicted to be involved in L-phenylalanine catabolic process and glutathione metabolic process. Predicted to act upstream of or within tyrosine catabolic process. Located in mitochondrion. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Orthologous to human GSTZ1 (glutathione S-transferase zeta 1). [provided by Alliance of Genome Resources, Apr 2022]
