RNase III is positively regulated by T7 protein kinase.
RNase III activity of Escherichia coli is stimulated 4-fold after infection with bacterial virus T7. The mechanism of stimulation is based on phosphate transfer to RNase III by the T7 coded protein kinase. In vitro synthesized protein kinase also stimulates RNase III. Serine is the phosphate acceptor.
