Time-course proteomics dataset to monitor protein-bound methionine oxidation in Bacillus cereus ATCC 14579

Data in Brief, 2018
Aerobic respiratory growth generates endogenous reactive oxygen species (ROS). ROS oxidize protein-bound methionine residues into methionine sulfoxide.

Sulfoxide-mediated Cys-Trp-selective bioconjugation that enables protein labeling and peptide heterodimerization [PDF]

A method was developed that enables the magnesium chloride (MgCl2)-activated S-acetamidomethyl cysteine sulfoxide (Cys(Acm)(O)) to induce the sp2(C−H) sulfenylation of the indole ring of Trp residues.

Monitoring of Methionine Sulfoxide Content and Methionine Sulfoxide Reductase Activity [PDF]

, 2017
The sulfur-containing amino acid methionine (Met) plays critical roles in protein synthesis, methylation, and sulfur metabolism. Both in its free form and in the form of an amino acid residue, it can be oxidized to the R and S diastereomers of methionine sulfoxide (MetO).

Methionine Sulfoxide Reduction and Assimilation in Escherichia coli: New Role for the Biotin Sulfoxide Reductase BisC

, 2004
International audienceABSTRACT Methionine ranks among the amino acids most sensitive to oxidation, which converts it to a racemic mixture of methionine- S -sulfoxide (Met-S-SO) and methionine- R -sulfoxide (Met-R-SO).

Reduction of DABS-L-methionine-dl-sulfoxide by protein methionine sulfoxide reductase from polymorphonuclear leukocytes: stereospecificity towards the l-sulfoxide

, 1994
A new synthetic substrate for protein methionine sulfoxide reductase is proposed. We show that extracts from human polymorphonuclear leukocytes can reduce 4-dimethylaminoazobenzene-4'-sulfonyl-L-methionine-dl-sulfoxide [DABS-L-Met-dl-(O)] to the ...

The Oxidized Protein Repair Enzymes Methionine Sulfoxide Reductases and Their Roles in Protecting against Oxidative Stress, in Ageing and in Regulating Protein Function

Antioxidants, 2018
Cysteine and methionine residues are the amino acids most sensitive to oxidation by reactive oxygen species. However, in contrast to other amino acids, certain cysteine and methionine oxidation products can be reduced within proteins by dedicated ...

From perfluoroalkyl aryl sulfoxides to ortho thioethers

Beilstein Journal of Organic Chemistry
Access to original ortho thioether derivatives was achieved through a [3,3]-rearrangement in a one-pot two-step protocol. Several aryl-SCF3 compounds are reported by variation of the nitrile or of the trifluoroalkyl sulfoxide starting material.
