... hydrophobic core (M88V) and the other in the protein–RNA interaction (T45S), decrease the stability of the capsid. Our findings illuminate the role of packing in the icosahedral lattice of the virus capsid. Experimental ... fluorescence. The protein shells of viruses generally have several key functions, including shielding of the nucleic acid, particle maturat...

Thus, the centering model is scaled up to the level of the global ... cognitively plausible limits of the atten- tional span. Walker, finally, claims that the content of the cache, rather than the intentional discourse segment stru...

... of linear sequences of tree-structured syllables. The question of structure above the level of the syllable is an interesting one. The use of metrical or tonal structure is clearly relevant ... to handle a root consisting of an arbitrary number of syllables. We need to allow for a poten- tially infinite number of syllables in a root, but we also need each sylla...

For determining the rates of Gt activation, the initial slopes of the first 30–60 s of data after illumination were fitted by linear regression. Molecular ... stability of the mutants and their ability to activate Gt could be correlated with the increase in size of the side-chain at position 51, pointing to...

Altogether, these data suggest a strong structural role for the terminal part of the C-terminal domain of ALSV integrase in the general folding of the enzyme and, hence, in its activity in the ... responsible for the integration of the DNA copy of the retroviral genome into the host cell DNA.
