Three-electron two-centred bonds and the stabilisation of cationic sulfur radicals [PDF]
Electronic communication in biological systems is fundamental to understanding protein signalling and electron hopping pathways. Frequently studied examples are cationic radical methionine and its functional derivatives.

Insights into the regulation of DMSP synthesis in the diatom Thalassiosira pseudonana through APR activity, proteomics and gene expression analyses on cells acclimating to changes in salinity, light and nitrogen [PDF]
Despite the importance of dimethylsulphoniopropionate (DMSP) in the global sulphur cycle and climate regulation, the biological pathways underpinning its synthesis in marine phytoplankton remain poorly understood.

EFFECT OF METHIONINE AND METHIONINE SULPHOXIMINE ON RAT BRAIN S‐ADENOSYL METHIONINE LEVELS [PDF]
Abstract—Rat brain SAM levels were markedly increased after methionine administration, whereas the convulsant, L‐methionine‐dl‐sulphoximine (MSO), produced a 35 per cent decrease in whole brain content of S‐adenosyl‐L‐methionine (SAM). When methionine was given in combination with MSO, SAM levels were not decreased. Studies on the regional distribution

Functional methionine synthase deficiency can be separated into two classes, cobalamin (Cbl) deficiency type E (CblE) and type G (CblG), which are the result of mutations that affect methionine synthase reductase or methionine synthase, respectively ...

Combination treatment with recombinant methioninase enables temozolomide to arrest a BRAF V600E melanoma in a patient-derived orthotopic xenograft (PDOX) mouse model. [PDF]
An excessive requirement for methionine termed methionine dependence, appears to be a general metabolic defect in cancer. We have previously shown that cancer-cell growth can be selectively arrested by methionine deprivation such as with recombinant ...

Methionine Dependence of Cancer
Tumorigenesis is accompanied by the reprogramming of cellular metabolism. The shift from oxidative phosphorylation to predominantly glycolytic pathways to support rapid growth is well known and is often referred to as the Warburg effect.

Developments in plant breeding for improved nutritional quality of soya beans I. Protein and amino acid content [PDF]
Soya beans, like other legumes, contain low concentrations of the nutritionally essential sulphur amino acid, methionine. Cysteine, although not an essential amino acid because it can be synthesized from methionine, also influences the nutritional ...
