Activating Compound

EC Number	Activating Compound	Comment	Organism	Structure
2.8.1.1	Butyrate	significantly increase of enzyme activity and expression in human colon cancer cell line HT-29	Homo sapiens
2.8.1.1	Sulfide	activating at 0.1 mM, inhibitory above 0.3 mM, in human colon cancer cell line HT-29	Homo sapiens

Application

EC Number	Application	Comment	Organism
2.8.1.1	medicine	in advanced colon cancers, expression of both thiosulfate sulfurtransferase and mercaptopyruvate sulfurtransferase is markedly reduced, the disease progression correlating with decrease in expression. In human colon cancer cell line HT-29, enzyme activity and expression are significantly increased by butyrate and by histone deacetylaseinhibition. Use of decrease in enzyme expression as a tumor marker for colorectal cancer	Homo sapiens
