Probing the lexicon in evaluating commercial MT systems Martin Volk University of Zurich Department of Computer Science, Computational Linguistics Group Winterthurerstr. 190, ... technical, linguistic and ergonomic issues. As part of the linguistic evaluation we wanted to determine the lexical coverage of the MT systems since only some of the systems provide...

... contribute to providing chromophore to melanopsin to maintain their light sensitivities. The expression and function of RPE65c in other cell types in the retina remains to be investigated. Earlier ... RPE65c in the inner retina, including Mu ¨ ller cells, but not in the RPE. Furthermore, double-immuno- staining of dissociated retinal cells using antibodies for RPE65c and gluta...

The remaining mutations alter amino acids located outside the ligand-binding pocket and ... locations of the missense mutation in the BTK PH domain; arginine 28 is in dark blue, encircled in red. Bottom left: SH2 domain. Right: kinase domain. The mutated residues ar...

... close to the N-terminal trans- membrane helix anchoring the protein to the inner membrane of mitochondria [27]. Therefore, the N-ter- minal segment (containing the residues protruding into the mitochondrial ... [85]. The histidine ligand coordination is therefore the discriminating factor for introducing a high-affinity copper-binding site in Sco proteins. Such a general mode...

... cOHB-modification of the C-terminal domain in the periplasm would increase the hydropho- bicity of hydrophilic segments in this domain, and thereby enable them to be incorporated into the bilayer. In support ... two-domain structure of OmpA, in which the N-terminal domain (residues 1–170) crosses the membrane eight times in antiparallel b-strands, and the 155-residue C-...

Although it remains unclear which of these hypotheses reflects most closely the cellular role of frataxin, their common denominator is a link between frataxin and iron. Interestin...
