WebMar 8, 2024 · CBS is a tetrameric hemeprotein that catalyzes condensation of serine and homocysteine to cystathionine. CS is a homodimer that catalyzes the formation of L-cysteine from O-acetyl-L-serine. Ser-dehyd catalyzes the conversion of L- or D-serine to pyruvate and ammonia. WebDec 5, 2003 · O -Phospho- l -homoserine was prepared from l -aspartic acid as described by Barclay et al. [11]. l -Cystathionine, O -phospho- l -serine, l -homoserine, O -succinyl- l -homoserine, 2 H 3 -iodomethane and l -homocystine were obtained from Sigma. Cystine and homocystine were reduced by reduction with 1,4-dithiolthreitol (DTT) as described below.
Homoserine (also called isothreonine) is an α-amino acid with the chemical formula HO2CCH(NH2)CH2CH2OH. l-Homoserine is not one of the common amino acids encoded by DNA. It differs from the proteinogenic amino acid serine by insertion of an additional -CH2- unit into the backbone. Homoserine, or its lactone form, is the product of a cyanogen bromide cleavage of a peptide by degr… WebJan 21, 2024 · HS Code: 2931900090: Summary: 2931900090. other organo-inorganic compounds.
