All enzymes reduce the energy of the transition state by pre-ordering the catalytic groups, e.g. the catalytic triad in serine proteases, the two Asps in HIV protease, the Cys residue i ...

Assembly of complete KIR haplotypes from a diploid individual

We show that linearizing and directly sequencing full-length fosmids simplifies the assembly problem such that it is possible to unambiguously assemble individual haplotypes for the highly repetitive 100-200 kb killer Ig-like receptor (KIR) gene loci of chromosome 19. A tiling of targeted fosmids ca ...
