Host factors involved in the growth of microvirid phage alpha 3.
Host factors involed in the growth of microvirid phage alpha3 were determined using various replication mutants of Escherichia coli. The viral multiplication was dependent on functional products of dnaE, dnaF(NRDA), DNAG, and dnaZ genes. Host functions directed by dnaA, so-alled dnaH, dnaI, and dnaP genes were dispensable for the viral growth. In contrast with phiZ174 and G4, alpha3 would grow sufficiently In dnaB and dnaC(D) mutants. The viral growth was not significantly affected by host polAts, seg, and groPC mutations.
