Recombinant human DDT protein
DDT is an enzyme that catayzes the tautomerization of D-dopachrome to give 5, 6-dihydroxyindole (DHI) . This protein belongs to the family of lyases, specifically the carboxy-lyases, which cleave carbon-carbon bonds. It shares a homologous amino acid sequence (33% identical) with the macrophage migration inhibitory factor (MIF) and possesses similar tautomerase activity. In addition, it may functions a proinflammatory cytokine. Recombinant human DDT, fused to His-tag at N-terminus, was expressed in E. coli and purified by using conventional chromatography.
