SUMMARY Two-component signal transduction, featuring highly conserved histidine kinases (HKs) and response regulators (RRs), is one of the most prevalent signalling schemes in prokaryotes. RRs function as phosphorylation-activated switches to mediate diverse output responses, mostly via transcription regulation. As bacterial genomes typically encode… (More)
How abstract knowledge is organised is a key question in cognitive science, and has clear repercussions for the design of artifical lexical resources, but is poorly understood. We present fMRI results for an experiment where participants imagined situations associated with abstract words, when cued with a visual word stimulus. We use a multivariate-pattern… (More)
The creation of China’s largest Russian-Chinese parallel corpus is described. Information on the overall structure of the corpus is laid out, selected texts are characterized, and the description is given of the processes of corpus development and automatic generation of a keyterm glossary. The search capabilities with inflectional paradigms are discussed… (More)
N-Glycosylation is a common form of protein post-translational modification in Pichia pastoris and greatly affects folding and secretion. The propeptide of the Pseudomonas aeruginosa elastase (PAE) is indispensable for proper folding and secretion of the enzyme. We have studied the effect of introducing N-glycosylation sites to the propeptide of the… (More)
The title compound, C(11)H(19)NO(6), is an important inter-mediate for the synthesis of cephalosporin derivatives. The N atom is in a planar configuration. In the crystal, mol-ecules are linked into zigzag layers parallel to (100) by O-H⋯O hydrogen bonds.
