Protein O-mannosylation represents an evolutionarily conserved, essential posttranslational modification with immense impact on a variety of cellular processes. In humans, O-mannosylation defects result in Walker-Warburg syndrome, a severe recessive congenital muscular dystrophy associated with defects in neuronal migration that produce complex brain and(More)
BACKGROUND The mode of action of the grass herbicides cinmethylin and 5-benzyloxymethyl-1,2-isoxazolines substituted with methylthiophene (methiozolin) or pyridine (ISO1, ISO2) was investigated. RESULTS Physiological profiling using a series of biotests and metabolic profiling in treated duckweed (Lemna paucicostata L.) suggested a common mode of action(More)
Fibroblasts grown in tissue culture from the skin of normal subjects have lysine-ketoglutarate reductase activity (lysine: alpha-ketoglutarate: triphosphopyridine nucleotide (TPNH) oxidoreductase (epsilon-N-[L-glutaryl-2]-L-lysine forming)). The activity of the enzyme is considerably reduced in the skin fibroblasts grown from three siblings with(More)
Lysine-ketoglutarate reductase (EC. deficiency in skin fibroblasts has been previously reported in patients with familial hyperlysinemia, providing an adequate explanation for the biochemical derangements noted clinically. In the present study, analysis of liver obtained at autopsy from a patient with familial hyperlysinemia confirmed the(More)
O-mannosylation is a crucial protein modification in eukaryotes that is initiated by the essential family of protein O-mannosyltransferases (PMTs). Here we demonstrate that in the model yeast Saccharomyces cerevisiae rhodanine-3-acetic acid derivatives affect members of all PMT subfamilies. Specifically, we used OGT2468 to analyse genome-wide(More)
BACKGROUND For novel herbicides identified in greenhouse screens, efficient research is important to discover and chemically optimise new leads with new modes of action (MoAs). RESULTS The metabolic and physiological response pattern to a herbicide can be viewed as the result of changes elicited in the molecular and biochemical process chain. These(More)
