Bend induced by the phage phi 29 transcriptional activator in the viral late promoter is required for activation.

Journal of molecular biology - 20 Feb 1990

Rojo F, Zaballos A, Salas M

Abstract excerpt

Transcription initiation from the Bacillus subtilis phage phi 29 late A3 promoter requires the viral protein p4, a transcriptional activator. Protein p4 binds to a region of the A3 promoter, located between nucleotides -50 and -100 relative to the transcription start site, that presents a sequence-directed curvature. This curvature is enhanced when protein p4 binds to the promoter. A number of deletion mutants at...
