Stereoselectivity of the Interactions of Thioglucoside Glucohydro- Lase and Epithiospecifier Protein from Various Sources*
نویسنده
چکیده
(S)-2-Hydroxy-3-butenylglucosinolate (epi-progoitrin) was converted to erythroand threo-1-eyano-2-hydroxy3,4-epithiobutanes by combinations of th~oglucoside glucohydrolase and epithiospecifier protein (ESP) from various sources. In all combinations studied the erythro/threo product ratio was about 1.4, except when the thioglucoside glucohydrolase was from Sinapis alba L. and the ESP from Brassica campestris in which case the ratio was about 1.8.

The Arabidopsis epithiospecifier protein promotes the hydrolysis of glucosinolates to nitriles and influences Trichoplusia ni herbivory.
Glucosinolates are anionic thioglucosides that have become one of the most frequently studied groups of defensive metabolites in plants. When tissue damage occurs, the thioglucoside linkage is hydrolyzed by enzymes known as myrosinases, resulting in the formation of a variety of products that are active against herbivores and pathogens. In an effort to learn more about the molecular genetic and...

متن کاملMapping of TP53 protein network using cytoscape software
TP53 acts as a tumor suppressor in cancer. It induces cell cycle arrest or apoptosis in response to cellular stress and damage. p53 gene alteration could cause uncontrolled cell proliferation.In the present study, we used TP53 gene as the seed in the construction of a protein-protein functional association network to identify genes that might involve in tumorgenesis process with TP53. TP53 prot...
