Sep 22, 2020 · DNA replication and repair depend on AAA+ ATPase protein complexes called clamp loaders that open and load ring-shaped sliding clamps onto DNA. Using cryogenic electron microscopy, we determined the first structure of the human clamp loader (RFC), which is in an autoinhibited conformation while bound to the sliding clamp (PCNA). We assign this to be a reaction intermediate …

Apr 01, 2001 · An archaeal clamp loader, replication factor C (RFC), consists of two proteins, the small subunit (RFCS) and large subunit (RFCL), whose sequences are both highly homologous to those of the eukaryotic RFC components. We have investigated the oligomeric structure of RFCS from Pyrococcus furiosus by electron microscopy using single-particle analysis. RFCS forms mostly ring-shaped …

Jul 24, 2001 · We have determined the crystal structure of the clamp loader small subunit (RFCS) from Pyrococcus furiosus. The six subunits, of which four bind ADP in their canonical nucleotide binding clefts, assemble into a dimer of semicircular trimers. The crescent-like architecture of each subunit formed by the three domains resembles that of the delta
