... behaviour of the wild- type enzyme and the D70G mutant. The lyotropic proper- ties of phosphate ions change with the pH. At pH 6.0, 94% of phosphate ions are H 2 PO 4 – , whereas at pH 8.0, 86% of phosphate ... the structure of water in the hydration shell of the enzyme active surface. This indicates that the hysteretic behaviour of BuChE with BzCh is not sensitive to change...

... three C-terminal fragments of histone H1.2 with different sizes were found to be potent inhibitors of furin with K i values around 2 · 10 )7 m, comparable with that of polyarginines such as L6R ... furin with a K i value of 4.6 · 10 )7 m. The identification of lysine-rich histone H1.2 and its C-terminal fragments as inhibitors of furin will undoubtedly pave the way for the...

Finally, we extended confidence-weighted learning with soft margins to handle the case where labels of training data are noisy. ... case of factored features. While we did not experiment with this, a natural extension consists in using all n-grams up to a certain order, thus providing back-off features and enabli...
