Erismann View Show abstract Clarence... WebOPHS derives from homoserine and is formed by homoserine kinase (HSK). To clarify the function of HSK in cellular metabolism, the E. coli HSK ortholog thrB was expressed in potato plants targeting the EcHSK protein to chloroplasts and to the cytosol. Both approaches resulted in up to 11 times increased total HSK enzyme activity.
WebO-Phosphohomoserine: Description: O-Phosphohomoserine, also known as homoserine phosphate, belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. O-Phosphohomoserine exists in all living species, ranging from bacteria to plants to humans.

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. WebO- phosphohomoserine is converted into threonine in an internal rearrangement, catalyzed by threonine synthase ( Fig. 7.13, 12). The enzyme, which is localized in the chloroplast, …
