Abstract:
:DNA cleavage by N-(O,O-diisopropyl)phosphoryl histidine(DIPP-His) is investigated by a submarine agarose electrophoresis technique. It was found that DIPP-His could cleave supercoiled DNAs and lambda DNA without the participation of divalent metal ions, while the histidine itself and N-(O,O-diisopropyl)phosphoryl alanine had no such function. Supercoiled pUC8 and pBR322 DNAs are cleaved to linear DNA and eventually fragments; lambda DNA is cleaved directly to fragments. Two mechanistic pathways are proposed for the cleavage reaction.
