WebSep 9, 2024 · The CBS gene encodes cystathionine beta-synthase (EC 4.2.1.22), which catalyzes the first irreversible step of transsulfuration. The enzyme conjugates homocysteine and serine to form cystathionine, which is subsequently converted into cysteine and alpha-ketobutyrate. Homocysteine can also undergo remethylation to form methionine. http://www.csi.org.cn/article/1373 photo crabe
