Cysteate synthase

Cysteate synthase is an enzyme with systematic name sulfite:O-phospho-L-serine sulfotransferase (phosphate-hydrolysing, L-cysteate-forming). This enzyme catalyses the following chemical reaction


 * O-phospho-L-serine + sulfite $$\rightleftharpoons$$ L-cysteate + phosphate

This enzyme is a pyridoxal-phosphate protein.
