WebCystathionine beta-synthase, along with vitamin B6, converts homocysteine to cystathionine (see Fig. 5-8). A deficiency of this enzyme leads to accumulation not only of homocysteine but also its precursor, methionine. The genetic disorder, homocystinuria, is attributable to a mutation on chromosome 21.
