The final model includes 24 chains representing 12 protein A polypeptides. Chains A-L represent the N-terminal floor segment built into the high-resolution EM density. Chains M-X represent a mainchain trace of the polymerase segment rigid body fit into the map and are included to give a more complete picture of the molecule. The polymerase mainchain trace was refined from an Alphafold prediction into a map obtained by symmetry expansion with subtraction. The polymerase map is uploaded as a separate entry. The two segments have separate chain IDs as it is unclear from the density which polymerase connects to which floor segment.
