Predicted to enable acireductone dioxygenase [iron(II)-requiring] activity. Predicted to be involved in L-methionine salvage from methylthioadenosine. Predicted to act upstream of or within methionine biosynthetic process. Predicted to be located in cytoplasm; nucleus; and plasma membrane. Is expressed in several structures, including alar plate midbrain region; head; optic tectum; optic vesicle; and pectoral fin bud. Orthologous to human ADI1 (acireductone dioxygenase 1).
