Structure of recombinant mouse L chain ferritin at 1.2 A resolution
Overview
The first ferritin structure refined at the atomic level has been achieved, on recombinant mouse L-chain apoferritin (rMoLF) crystals. These latter, diffract to 1.2 A resolution under cryogenic conditions. When cryo-cooling, the sample, the thermal disorder usually observed at room temperature is, reduced and the low-temperature structure reveals several details, concerning the protein putative active sites and their properties. Within, the pores built up by the molecular three-fold symmetry axes, the iron, entry route to the ferritin cavity, residues H118, D131 and E134, exhibit, alternate conformations associated with the binding of partially hydrated, cadmium ions, a metal used as a crystallization agent. At the mineral, ferrihydrite nucleation center, the electron density maps ... [(full description)]
