| Comments |
A multifunctional pyridoxal-phosphate protein. The enzyme cleaves a carbon-sulfur bond, releasing?L-cysteine and an unstable enamine product that tautomerizes to an imine form, which undergoes a hydrolytic deamination to form 2-oxobutanoate and ammonia. The latter reaction, which can occur spontaneously, can also be catalysed by EC?3.5.99.10, 2-iminobutanoate/2-iminopropanoate deaminase. Also catalyses the conversion of?L-homoserine to 2-oxobutanoate and ammonia, of?L-cystine to thiocysteine, pyruvate and ammonia, and of?L-cysteine to pyruvate, hydrogen sulfide and ammonia. |
