General description

Cystathionine-β-synthase (CBS) also known as histone promoter control protein Hip4, is encoded by the gene mapped to human chromosome 21q22.3. CBS is a homotetramer containing 63kDa subunits. The encoded protein comprises C-terminal domain with a negative regulatory region, the middle domain with the catalytic core and heme-containing N-terminal domain.
The protein encoded by this gene acts as a homotetramer to catalyze the conversion of homocysteine to cystathionine, the first step in the transsulfuration pathway. The encoded protein is allosterically activated by adenosyl-methionine and uses pyridoxal phosphate as a cofactor. Defects in this gene can cause cystathionine beta-synthase deficiency (CBSD), which can lead to homocystinuria. (provided by RefSeq)

Biochem/physiol Actions

Cystathionine-β-synthase (CBS) catalyzes the first step in the transsulfuration pathway, where serine and homocysteine is converted to cystathionine and water. In addition, it also acts as a catalyst for various alternative reactions involved in the synthesis of hydrogen sulfide, a novel neuromodulator in the brain. Deficiency of the gene is associated with the development of an autosomal recessive disorder, homocystinuria.
