|Conservation in nuoK||Back to subunit list|
The membrane sector of E. coli Complex I is shown with each of the 6 subunits colored a different color. The peripheral arm and subunit H of the membrane arm are missing.
Subunit K is colored according to conservation. Magenta is most conserved, cyan is least conserved. Several lipids, detergents and internal water molecules are shown in space filling. Isolated view of subunit K.
