'''Structural comparison of the oxidized ternary electron transfer complex of methylamine dehydrogenase, amicyanin and cytochrome c551i from Paracoccus denitrificans with the substrate-reduced, copper free complex at 1.9 A resolution.'''<br />


==Overview==
==Structural comparison of the oxidized ternary electron transfer complex of methylamine dehydrogenase, amicyanin and cytochrome c551i from Paracoccus denitrificans with the substrate-reduced, copper free complex at 1.9 A resolution.==
The crystal structure of a ternary protein complex has been determined at 2.4 angstrom resolution. The complex is composed of three electron transfer proteins from Paracoccus denitrificans, the quinoprotein methylamine dehydrogenase, the blue copper protein amicyanin, and the cytochrome c551i. The central region of the c551i is folded similarly to several small bacterial c-type cytochromes; there is a 45-residue extension at the amino terminus and a 25-residue extension at the carboxyl terminus. The methylamine dehydrogenase-amicyanin interface is largely hydrophobic, whereas the amicyanin-cytochrome interface is more polar, with several charged groups present on each surface. Analysis of the simplest electron transfer pathways between the redox partners points out the importance of other factors such as energetics in determining the electron transfer rates.

== Function ==
[https://www.uniprot.org/uniprot/DHMH_PARDE DHMH_PARDE] Methylamine dehydrogenase carries out the oxidation of methylamine. Electrons are passed from methylamine dehydrogenase to amicyanin.
