ID   2.5.1.76
DE   cysteate synthase.
CA   H(+) + O-phospho-L-serine + sulfite = L-cysteate + phosphate.
CC   -!- It is highly specific for O-phospho-L-serine and sulfite.
CC   -!- The reaction proceeds through a dehydroalanine (2-aminoacrylic acid)
CC       intermediate.
CC   -!- The enzyme from Methanosarcina acetivorans is evolutionarily related
CC       to EC 4.2.3.1, but the reaction is more similar to that of
CC       EC 2.5.1.65.
