Glutathione conjugation of aflatoxin B1 exo- and endo-epoxides by rat and research-subject glutathione S-transferases
Instead of either-or, they work best together
To address this question, we mutated Tyr110 in the CPYS-motif of ScGrx7 as a candidate residue that might contribute to the glutathione activator site (see Discussion for details) and performed a preliminary study with wild-type ScGrx7 as a control
Model-specific findings should not be generalized or read as use guidance for research-use-only materials
Both these methylation reactions are vital for growth and cell reproduction.[9][10] Methionine, a sulfur-containing, essential amino acid, is a precursor of S-adenosylmethionine, a cofactor for one-carbon metabolism and the final methyl donor for the methylation of DNA, RNA, proteins, and phospholipids.[11] The methionine synthase plays a paramount role in the synthesis of nitrogenous bases (purines and pyrimidines) involved in the formation of DNA
