Glycosylphosphatidylinositol transamidase (GPI-T) is a complicated, membrane-bound, multi-subunit enzyme that catalyzes an essential post-translational modification. This enzyme attaches GPI anchors to the C-termini of various proteins that contain a proper GPI-T signal sequence. Gpi8, Gaa1, Gpi16, Gpi17 and Gab1 are the five known subunits that may encompass the fungal GPI-T; Gpi8 is the catalytic subunit, but the functions of the other subunits remain essentially unknown. In humans, different GPI-T subunits are …

The -aminooxy derivative of the Thomsen–Friedenreich tumor associated carbohydrate antigen has been synthesized in 11 steps utilizing a D-GalN3 acceptor carrying a pre-installed -N-hydroxysuccinimidyl moiety. The natural linkage was prepared in high selectivity employing a suitably protected D-GalN3-thioglycoside donor with N-hydroxysuccinimide. With access to -TF-ONH2, the preparation of the TF-PS A1 vaccine candidate ensued smoothly through oxime bond formation. This construct …

The advent of complete-genome genotyping across phenotype cohorts has provided a rich source of information for bioinformaticians. However the search for SNPs from this data is generally performed on a study-by-study case without any specific hypothesis of the location for SNPs that are predictive for the phenotype. We have designed a method whereby very large SNP lists (several gigabytes in size), combining several genotyping studies at once, can be sorted and traced back to their ultimate consequence in protein structure. Given a working hypothesis, researchers are able to easily search whole genome genotyping data for SNPs that link genetic locations …
