Effects of recB, recF and uvrA mutations on Weigle reactivation of lambda phages in Escherichia coli K12 treated with 8-methoxypsoralen or angelicin and 365-nm light.

Abstract

The extent of Weigle reactivation (W-R) of lambda c+ phages treated with bifunctional 8-methoxypsoralen and 365-nm light (8-MOP + UVA) and with monofunctional angelicin and 365-nm light (ANG + UVA) were compared in Escherichia coli strains with different excision repair and recombinational capacities. In uvrA6 host cells, irradiation of the cells with 254… (More)
