Elevated cystathionine
WebLanthionine is an unusual non-protein amino acid, naturally occurring as a byproduct of hydrogen sulfide (H 2 S) biosynthesis from cysteine in vivo [1,2].This reaction is catalyzed by three enzyme systems in humans, cystathionine-β-synthase (CBS) or cystathionase (cystathionine-γ-lyase; CSE), and 3-mercaptopyruvate sulfurtransferase (MST), which … Web- Insufficient B6, B12, or folate have been shown to result in elevated blood levels of cystathionine. - Elevations of cystathionine has been noted in neural tumors, renal defects, or defects in the conversion of homocysteine to methionine. - A cystathionine beta-synthase (CBS) deficiency can lead to a decrease in cystathionine. ...
