Dodecameric protein
A dodecameric protein has a quaternary structure consisting of 12 protein subunits in a complex. Dodecameric complexes can have a number of subunit 'topologies', but typically only a few of the theoretically possible subunit arrangements are observed in protein structures.
A dodecamer is a protein complex with 12 protein subunits.
A common subunit arrangement involves a tetrahedral distribution of subunit trimers. Another observed arrangement of subunits puts two rings of six subunits side by side along the sixfold axis.Dodecameric proteins include
