Cystathione 尾-synthase
WebCystathionine γ-synthase catalyzes replacement of the succinyl group of O-succinylhomoserine by cysteine to yield cystathionine, a step in methionine biosynthesis in Salmonella. The enzyme catalyzes rapid exchanges of both α and β hydrogen atoms in many amino acids that are not otherwise substrates.

Cystathionine 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.
WebClassic homocystinuria due to cystathionine beta-synthase deficiency can present in childhood or adolescence with arterial ischemic or venous infarction. Associated features include developmental delay, marfanoid habitus, high myopia, lens dislocation, and osteopenia. Complexion is often pale, and there may be malar flushing or livedo reticularis.
