Description
Springer Viral Membrane Proteins Structure Function And Drug Design by Wolfgang B. Fischer
In Viral Membrane Proteins: Structure, Function, and Drug Design, Wolfgang Fischer summarizes the current structural and functional knowledge of membrane proteins encoded by viruses. In addition, contributors to the book address questions about proteins as potential drug targets. The range of information covered includes signal proteins, ion channels, and fusion proteins.This book has a place in the libraries of researchers and scientists in a wide array of fields, including protein chemistry, molecular biophysics, pharmaceutical science and research, bioanotechnology, molecular biology, and biochemistry.show more Part I.
