WebMar 29, 2024 · 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. This gene is a major contributor to cellular hydrogen sulfide production. fizan compact 4 walking poleWebDeficiencies of methionine adenosyltransferase, cystathionine β-synthase, and cystathionine γ-lyase have been described. The first leads to hypermethioninemia but no other clinical abnormality. The second leads to hypermethioninemia, hyperhomocysteinemia, and homocystinuria. The disorder is transmitted as an autosomal recessive trait. cannon gas cooker manualWebCystathionine 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.
