摘要
The Cdc6 proteins from the archaeon Methanothermobacter thermautotrophicus were previously shown to bind double-stranded DNA. It is shown here that the proteins also bind single-stranded DNA. Using minichromosome maintenance (MCM) helicase mutant proteins unable to bind DNA, it was found that the interaction of MCM with Cdc6 inhibits the DNA binding activity of Cdc6.
