Abstrakt: The mechanism of the inhibitory action of 1-beta-D-arabinofuranosyl-E-5-(2-bromovinyl) uracil triphosphate (BV-araUTP) on DNA synthesis by Escherichia coli DNA polymerase I Klenow fragment was studied. Acting as a chain terminator, BV-araUTP inhibited DNA synthesis by Klenow fragment more effectively than 2',3'-dideoxythymidine triphosphate (ddTTP). However, the incorporation sites of BV-araU monophosphate were restricted at consecutive dTMP sequence whereas ddTMP was incorporated at every dTMP site.
