cystathionine beta-Synthase

Preferred Label : cystathionine beta-Synthase;

MeSH definition : A multifunctional pyridoxal phosphate enzyme. In the second stage of cysteine biosynthesis it catalyzes the reaction of homocysteine with serine to form cystathionine with the elimination of water. Deficiency of this enzyme leads to HYPERHOMOCYSTEINEMIA and HOMOCYSTINURIA. EC 4.2.1.22.;

MeSH synonym : serine sulfhydrase; beta-thionase; beta thionase; sulfhydrase, serine; cystathionine synthetase; synthetase, cystathionine; beta-synthase, cystathionine; cystathionine beta synthase;

MeSH CAS label : L-Serine hydro-lyase (adding homocysteine);

MeSH Related Number : 9023-99-8 (CAS RN);
