dodecamer	the dodecameric complex of flavoprotein reductase subunits (SiRFP) and hemoprotein oxidase subunits (SiRHP). Small-angle neutron scattering solution structures of the interaction of SiRFP show, how both SiRHP binding to, and reduction of, SiRFP positions SiRFP for electron transfer between the subunits	Escherichia coli
