Mini-chromosome Maintenance (MCM) proteins play an essential role in both initiation and elongation phases of DNA replication in Eukarya. Genes encoding MCM homologs are present also in the genomic sequence of Archaea and the MCM-like protein from the euryarchaeon Methanobacterium thermoautotrophicum (Mth MCM) was shown to possess a robust ATP-dependent(More)
Here we report the isolation and characterization of a clamp-loader complex from the thermoacidophilic archaeon Sulfolobus solfataricus (SsoRFC). SsoRFC is a hetero-pentamer composed of polypeptides of 37 kDa (small subunit) and 46 kDa (large subunit), which possess primary structure similarity with human replication factor C p40 and p140 subunits,(More)
Cdc6 proteins play an essential role in the initiation of chromosomal DNA replication in Eukarya. Genes coding for putative homologs of Cdc6 have been also identified in the genomic sequence of Archaea, but the properties of the corresponding proteins have been poorly investigated so far. Herein, we report the biochemical characterization of one of the(More)
