Abstract excerpt

We have described a novel essential replicative DNA helicase from Bacillus anthracis, the identification of its gene, and the elucidation of its enzymatic characteristics. Anthrax DnaB helicase (DnaB(BA)) is a 453-amino-acid, 50-kDa polypeptide with ATPase and DNA helicase activities. DnaB(BA) displayed distinct enzymatic and kinetic properties. DnaB(BA) has low single-stranded DNA (ssDNA)-dependent ATPase...
