Greek key barrel to split the region.

Some bacteria are able to use extracellular mineral forms of iron and manganese, as a respiratory electron acceptor. In

oneidensis Shewanella is due decaheme cytochromes, which are located on the surface of bacterial cells at the ends of trans-outer membrane channels

transfer of strattera electrons. Cytochromes cell surface can potentially play multiple roles in mediating electron transfer

directly insoluble electron sinks, catalyze the electronic exchange of flavin shuttles electrons or participate in extracellular

intercytochrome electronic exchange of appendages nanoprovidnyka. We present 3. Second crystal structure of one of these decaheme

cytochromes, MtrF, which allows the spatial organization of 10 heme be visualized for the first time. Heme is

organized in four areas in a unique crossed conformations in which the chess 65th octaheme chain crosses >> << length protein and is divided in half flat 45th tetraheme chain that connects the two extended Greek key barrel to split the region. Molecular structure provides an understanding of how the reduction of insoluble substrate (eg, minerals), soluble substrates (eg

Flavin) and cytochrome redox partners may be possible to bet on different ends of a trifurcated electron transport

chain on the cell surface. . << >>
