homoserine

homoserine
Amino-4-hydroxybutyric acid; a hydroxyamino acid differing from serine in the possession of an additional CH2 group. An intermediate in the biosynthesis of cystathionine, threonine, and methionine.
- h. deaminase SYN: cystathionine γ-lyase.
- h. dehydratase SYN: cystathionine γ-lyase.
- h. lactone the cyclic ester ( i.e., the δ-lactone) of h.; formed by the reaction of cyanogen bromide on methionyl residues in peptides and proteins.
