DDT (gene)
D-dopachrome decarboxylase is an enzyme that in humans is encoded by the DDT gene.
D-dopachrome tautomerase converts D-dopachrome into 5,6-dihydroxyindole. The DDT gene is related to the macrophage migration inhibitory factor in terms of sequence, enzyme activity, and gene structure. DDT and MIF are closely linked on chromosome 22.
