WebCystathionine is an intermediary metabolite that is formed in the sequential enzymatic conversion of methionine to cysteine. Cystathionine is normally detected at very low levels in plasma. It is found between homocysteine and cysteine and is formed by the enzyme cystathionine beta-synthase ( CBS ). WebNov 11, 2011 · Cystathionine beta synthase (CBS) is the key regulatory enzyme for the transsulfuration pathway, which is responsible for the conversion of methionine to cysteine.
