Bacterial DNA clamp

thingiverse

A DNA clamp, also referred to as a sliding clamp, enhances processivity in DNA replication by encircling double-stranded DNA and serving as a mobile tether for numerous partner proteins like replicative DNA polymerases. In E. coli, it is composed of two identical subunits that together form the clamp structure. The model portrays a crystal structure of this clamp (PDB entry 4K3S), which was created using VMD software and requires two monomer copies to form a dimer.
