Herpes simplex virus (HSV) entry and cell–cell fusion require the envelope proteins gD, gH/gL and gB. We propose that receptor-activated conformational changes to gD activate gH/gL, which then triggers gB (the fusogen) into an active form. To study this dynamic process, we have adapted a dual split protein assay originally developed to study the kinetics of human immunodeficiency virus (HIV) mediated...
Disorders of oxidative phosphorylation and mitochondrial function can be caused from mutations involving both mitochondrial DNA (mtDNA) or mitochondrial-targeted nuclear DNA genes. Progressive depletion of mtDNA is one mechanism of mitochondrial dysfunction leading to human disease, which is the end result of loss of the sufficient mtDNA-encoded proteins for normal electron transport chain function...
The photoinduced dimerization of adjacent pyrimidines in DNA is influenced in predictable ways by DNA conformation. A method is described for determining patterns of pyrimidine dimer formation under conditions in which the chromatin is minimally perturbed. The relation of such patterns to the conformation of nucleosomal core DNA and linker DNA, as well as the interaction of histone H1 with nucleosomal...
