taurine degradation via aerobic pathway Degradation of taurine (2-aminoethanesulfonic acid), an organic acid that is abundant in the tissues of many animals (metazoa). Taurine is also found in plants, fungi, and some bacterial species, but at lower levels. Taurine is a derivative of the sulphur-containing (sulfhydryl) amino-acid, cysteine. 2-aminoethanesulfonic acid degradation via aerobic pathway pathway KEGG:map00430 KEGG:map01100 UPa:UPA00336 organosulfur degradation
