SV40 VP1 major capsid protein in its self-assembled form allows VP1 pentamers to coat various types of artificial beads in vitro regardless of their sizes and shapes
Abstract The icosahedral capsid structure of simian virus 40 (diameter, 45nm) consists of 72 pentameric subunits, with each subunit formed by five VP1 molecules. Electron microscopy, immuno-gold labeling, and ζ-potential analysis showed that...

Ultraviolet transient absorption, transient grating and photon echo studies of aqueous tryptophan
Abstract We compare UV transient grating (TG) experiments of aqueous tryptophan with transient absorption (TA) and fluorescence up-conversion measurements. The TG and TA signals show a bi-exponential rise with sub-ps and ps time constants, which are ...

How hydrogen bonds impact P-glycoprotein transport and permeability
Abstract The requirement to cross a biological membrane can be a complex process especially if multidrug transporters such as P-gp must be considered. Drug partitioning into the lipid membrane and efflux by P-gp are tightly coupled processes wherein ...
