Figure 1: Semiquinone is unstable as a free radical, but its stability can be tailored in a protein environment. Measurements were performed with a Bruker EMX EPR spectrometer (Bruker Instruments).

Researchers have used rational design to create a synthetic metalloprotein with an active site that looks and acts like that of the native version. The working model of nitric oxide reductase (NOR) ...

An international team of scientists, led by the University of Liverpool, has produced structural movies of a key enzyme involved in a biological pathway of greenhouse gas production that offer new ...

A new paper reports a truly radical development: Researchers designed a metalloprotein that can stabilize a reactive organic radical that is not normally stable in water. The work is a first step ...
