The Front Cover shows an artistic view of E.coli cells and two spin-labeled recombinantly
produced proteins, which can be inserted into the cells via osmotic shock or electroporation
methods. The primary sequence of the proteins is schematically shown with the one-letter
amino acid code, and cysteine residues are functionalized with the two new gem diethyl
nitroxide spin labels designed to better sustain the reducing cellular environment.
