Increased deoxyribonucleic acid (DNA) polymerase activity is found in soluble extracts from a polymerase I-negative mutant ofBacillus subtilis after infection with temperate phage SPO2, or after induction of SPO2 prophage in lysogenic derivatives of this mutant. No increased enzyme activity is found after SPO2 infection in the presence of chloramphenicol. Infection of the polymerase-negative mutant with the DNA-negative sus mutant SPO2 L244 gives no increased enzyme activity, whereas infection with DNA-negative sus mutant SPO2 J385 gives enzyme activities comparable to those found in wild-type infected cells. These findings suggest that SPO2 determines a DNA polymerase activity essential for synthesis of phage DNA.
