Cysteine 19-27 methionine adenosyltransferase 1A Homo sapiens 62-65 21994917-2 2011 For understanding and confirming the mechanism of the reaction, the electrochemical behaviors of Michael addition reaction of two model compounds, cysteine (CYS) and glutathione (GSH), towards the catechol-terminated SAMs have been studied. Cysteine 147-155 methionine adenosyltransferase 1A Homo sapiens 217-221 21994917-2 2011 For understanding and confirming the mechanism of the reaction, the electrochemical behaviors of Michael addition reaction of two model compounds, cysteine (CYS) and glutathione (GSH), towards the catechol-terminated SAMs have been studied. Cysteine 157-160 methionine adenosyltransferase 1A Homo sapiens 217-221 21828453-0 2009 Growth dynamics of L-cysteine SAMs on single-crystal gold surfaces: a metastable deexcitation spectroscopy study. Cysteine 19-29 methionine adenosyltransferase 1A Homo sapiens 30-34 16413417-11 2006 Increased flux of (13)C-labeled methionine to S-adenosylhomocysteine (SAH) in A549 demonstrated that SAM"s methyl group was utilized, and increased formation of cystathionine indicated that at least part of SAM generated was directed toward cysteine/GSH in the transsulfuration pathway. Cysteine 60-68 methionine adenosyltransferase 1A Homo sapiens 101-106 9699005-8 1998 MAT inactivation originates on the specific and covalent modification of the sulphydryl group of cysteine residue 121. Cysteine 97-105 methionine adenosyltransferase 1A Homo sapiens 0-3 9337154-3 1997 In vitro studies using pure liver recombinant enzyme and mutants of MAT, where each of the 10 cysteine residues of the enzyme subunit were individually changed to serine by site-directed mutagenesis, identified cysteine 121 as the site of molecular interaction between H2O2 and liver MAT. Cysteine 211-219 methionine adenosyltransferase 1A Homo sapiens 68-71 9337154-3 1997 In vitro studies using pure liver recombinant enzyme and mutants of MAT, where each of the 10 cysteine residues of the enzyme subunit were individually changed to serine by site-directed mutagenesis, identified cysteine 121 as the site of molecular interaction between H2O2 and liver MAT. Cysteine 211-219 methionine adenosyltransferase 1A Homo sapiens 284-287 9337154-4 1997 Cysteine 121 is specific to the hepatic enzyme and is localized at a "flexible loop" over the active site cleft of MAT. Cysteine 0-8 methionine adenosyltransferase 1A Homo sapiens 115-118 9337154-5 1997 In vivo studies, using wild-type Chinese hamster ovary (CHO) cells and CHO cells stably expressing liver MAT, demonstrate that the inactivation of MAT by H2O2 is specific to the hepatic enzyme, resulting from the modification of the cysteine residue 121, and that this effect is mediated by the generation of the hydroxyl radical. Cysteine 233-241 methionine adenosyltransferase 1A Homo sapiens 105-108 9337154-5 1997 In vivo studies, using wild-type Chinese hamster ovary (CHO) cells and CHO cells stably expressing liver MAT, demonstrate that the inactivation of MAT by H2O2 is specific to the hepatic enzyme, resulting from the modification of the cysteine residue 121, and that this effect is mediated by the generation of the hydroxyl radical. Cysteine 233-241 methionine adenosyltransferase 1A Homo sapiens 147-150 9337154-3 1997 In vitro studies using pure liver recombinant enzyme and mutants of MAT, where each of the 10 cysteine residues of the enzyme subunit were individually changed to serine by site-directed mutagenesis, identified cysteine 121 as the site of molecular interaction between H2O2 and liver MAT.
