The integrase class site specific recombinases FLP from Saccharomyces cerevisiae, and Cre from bacteriophage P1, have been extensively used to direct DNA rearrangements in heterologous organisms. Although their reaction mechanisms have been relatively well characterised, little comparative analysis of the two enzymes has been published. We present a(More)
MOTIVATION We describe a Brownian dynamics model for the folding of the chromatin fiber based on the model of Woodcock et al. (Proc Natl Acad Sci USA, 90, 9021-9025, 1993). The model takes into account the elastic properties of the DNA as well as the electrostatic interaction and nucleosomal excluded-volume interaction. The solvent is described as a viscous(More)
The hydration properties of a protein are important determinants of its structure and function. Here, modular neural networks are employed to predict ordered hydration sites using protein sequence information. First, secondary structure and solvent accessibility are predicted from sequence with two separate neural networks. These predictions are used as(More)
Creating highly articulated miniature structures requires assembling a large number of small parts. This is a very challenging task and increases cost of mechanical assemblies. Insert molding presents the possibility of creating a highly articulated structure in a single molding step. This can be accomplished by placing multiple metallic bearings in the(More)
