Thermoplasma acidophilum Cdc6 protein stimulates MCM helicase activity by regulating its ATPase activity

The minichromosome maintenance (MCM) proteins are thought to function as the replicative helicases in archaea. In most archaeal species studied, the interaction between MCM and the initiator protein, Cdc6, inhibits helicase activity. To date, the only exception is the helicase and Cdc6 proteins from the archaeon Thermoplasma acidophilum. It was previously… CONTINUE READING
