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)
Lysine-ketoglutarate reductase (saccharopine dehydrogenase (NADP+, lysine-forming) EC 1.5.1.8) from human liver has been partially purified and characterized. A spectrophotometric assay is described. The Michaelis constants have been determined for lysine (1.5-10-3 M), alpha-ketoglutarate (1-10-3 M) and NADPH (8-10-5 M). The pH optimum is 7.8. The enzyme is(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)
