Abstract

Kinetics of the Escherichia coli PriA helicase interactions with the ssDNA has been studied, using the fluorescence stopped-flow technique. Experiments have been performed with a series of fluorescent etheno derivatives of ssDNA adenosine oligomers, differing in the number of nucleotide...read more

DNA Helicases

DNA helicases are motor enzymes that move along the DNA phosphodiester backbone separating two DNA strands using energy derived from ATP hydrolysis. They are essential for several cellular processes including DNA replication and transcription. Here is the latest research.
