WebJan 13, 2011 · Cysteine, an essential amino acid, is the primary substrate for the reaction ( Figure 22.1). Cysteine is oxidized to cysteine sulfinic acid by cysteine dioxygenase. The cysteine sulfinic acid is further decarboxylated to hypotaurine by cysteine sulfinic acid decarboxylase. Hypotaurine is then converted to taurine by hypotaurine dehydrogenase. WebCysteine aminotransferase (CAT) per se, as well as a component of the CAT: 3-mercaptopyruvate sulfurtransferase (MST) axis, is pivotal for this metabolic rewiring, constituting a central mechanism in amino acid metabolism and fulfilling the metabolic needs of cancer cells, thereby supplying other di erent pathways. portland maine ballot 2021
