Molecular modeling, dynamics, and an insight into the structural inhibition of cofactor independent phosphoglycerate mutase isoform 1 fromWuchereria bancroftiusing cheminformatics and mutational studies

O. P. Sharma、Yellamandayya Vadlamudi、Qinghua Liao 等 5 位作者2012-08-22Journal of Biomolecular Structure and Dynamics

Phosphoglycerate mutase catalyzes the interconversion between 2-phosphoglycerate and 3-phosphoglycerate in the glycolytic and gluconeogenic pathways. They exist in two unrelated forms, that is either cofactor (2,3-diphosphoglycerate) dependent or cofactor-independent. These two enzymes have no similarity in amino acid…

Microscopic models of mode-coupling theory: The $\hbox{\sf{\bfseries{F}}}_{12}$F12 scenario

Jeferson J. Arenzon、Mauro Sellitto2012-08-22The Journal of Chemical Physics

We provide extended evidence that mode-coupling theory (MCT) of supercooled liquids for the F(12) schematic model admits a microscopic realization based on facilitated spin models with tunable facilitation. Depending on the facilitation strength, one observes two distinct dynamical glass transition lines--continuous a…

Drying Transition of Water Confined between Hydrophobic Pillars

Hyojeong Kim、Joyanta K. Saha、Joonkyung Jang2012-08-22The Journal of Physical Chemistry C

The phase behavior of the water confined between hydrophobic pillars was studied by using a simple thermodynamic theory and the lattice gas Monte Carlo simulation. The drying transition of water with decreasing spacing between pillars is related to the Wenzel (WZ) to Cassie–Baxter (CB) transition of droplet. Our theor…
