Cysteine sulfinic acid decarboxylase (CSAD) mediates the decarboxylation of 3-sulfinoalanine to produce hypotaurine. CSAD functions as a homodimer and requires pyridoxal phosphate as a cofactor (Winge et al. 2015). Purification, characterisation and activity of CSAD has been determined from rat liver (Guion-Rain et al. 1975).
