Cystathionine Chemical Properties,Uses,Production

Chemical Properties

White Crystalline Solid

Uses

Intermediate in transsulfuration whereby the mammal transfers the sulfur of methionine via homocysteine to cysteine

Uses

Intermediate for transsulfuration whereby a mammal transfers the sulfur of methionine via homocysteine to cysteine.

Definition

ChEBI: A modified amino acid generated by enzymic means from homocysteine and serine.

Biological Activity

Cystathionine is an intermediate in the biosynthesis of the amino acid cysteine. Cystathionine is used as a substrate to differentiate and analyze cystathionine gamma-lyase(s).
