Reduction of methionine sulfoxide to methionine by Escherichia coli.
L-Methionine-dl-sulfoxide can support the growth of an Escherichia coli methionine auxotroph, suggesting the presence of an enzyme(s) capable of reducing the sulfoxide to methionine. This was verified by showing that a cell-free extract of E. coli catalyzes the conversion of methionine sulfoxide to methionine. This reaction required reduced nicotinamide adenine dinucleotide phosphate and a gene...
متن کاملMethionine sulfoxide reductase A is a stereospecific methionine oxidase.
Methionine sulfoxide reductase A (MsrA) catalyzes the reduction of methionine sulfoxide to methionine and is specific for the S epimer of methionine sulfoxide. The enzyme participates in defense against oxidative stresses by reducing methionine sulfoxide residues in proteins back to methionine. Because oxidation of methionine residues is reversible, this covalent modification could also functio...
متن کاملSelenium and Methionine Sulfoxide Reduction.
Selenium is an essential trace element because it is present in proteins in the form of selenocysteine residue. Functionally characterized selenoproteins are oxidoreductases. Selenoprotein methionine-R-sulfoxide reductase B1 (MsrB1) is a repair enzyme that reduces ROS-oxidized methionine residues in proteins. Here, we explored a possibility that reversible methionine oxidation is also a mechani...
متن کاملErratum to “Decreased Phosphorylation and Increased Methionine Oxidation of α-Synuclein in the Methionine Sulfoxide Reductase A Knockout Mouse”
Previously, we have showed that overexpression of methionine-oxidized α-synuclein in methionine sulfoxide reductase A (MsrA) null mutant yeast cells inhibits α-synuclein phosphorylation and increases protein fibrillation. The current studies show that ablation of mouse MsrA gene caused enhanced methionine oxidation of α-synuclein while reducing its own phophorylation levels, especially in the h...

THE DIHEDRAL ANGLE BETWEEN THE PLANES OF TWO AROMATIC RINGS IN THE TITLE COMPOUND [SYSTEMATIC NAME: 3-benzoyl-5-chloro-pyrimidine-2,4(1H,3H)-dione], C(11)H(7)ClN(2)O(3), is 86.79 (6)°. Centrosymmetric dimers formed by N-H⋯O hydrogen bonds are linked through C-H⋯O inter-actions, forming a two-dimensional network parallel to (10).
