of the P2 and P4 late promoters.  ...  We have carried out a mutational scan of the upstream region of the bacteriophage P2 FETUD late operon promoter, P F , which spans an element of hyphenated dyad symmetry that is conserved among all six  ...  The four P2 late promoters (2, 3) and the two P4 late promoters (5, 6) share features typical of positively regulated bacterial promoters recognized by RNA polymerase carrying the 70 subunit.  ...

Bacteriophage PSP3 and phiR73 activator proteins: analysis of promoter specificities

B Julien, R Calendar
1996 Journal of Bacteriology  
In contrast, the satellite phage activators function better on the four late P2 promoters and on the P4 late leftward promoter.  ...  We purified one activator encoded by a P2-like phage and an activator from a satellite phage and determined their binding sites within the P2 and P4 late promoters.  ...  ACKNOWLEDGMENTS We thank Leonard Bullas, Gail Christie, Elisabeth Haggård-Ljungquist, and Bob Simons for strains and plasmids.  ...

Mechanisms of genome propagation and helper exploitation by satellite phage P4

B H Lindqvist, G Dehò, R Calendar
1993 Microbiological reviews  
P4 turns on the expression of helper phage late genes by two mechanisms: derepression of P2 prophage and transactivation of P2 late-gene promoters.  ...  The P4 genome (11,624 bp) and the P2 genome (33.8 kb) share homologous cos sites of 55 bp which are essential for generating 19-bp cohesive ends but are otherwise dissimilar.  ...  about 100 bp downstream ofpl, and shares similarity with P2 and P4 late promoters.  ...

Functions involved in bacteriophage P2-induced host cell lysis and identification of a new tail gene

R Ziermann, B Bartlett, R Calendar, G E Christie
1994 Journal of Bacteriology  
Gene Y encodes a polypeptide with striking similarities to the family of holin proteins exemplified by gpS of phage lambda, and the Yam mutant displayed the expected properties of a holin mutant.  ...  Both orf19 (gene X) and orf20 (gene Y) encode essential functions, whereas orf22 (lysA) and orf23 (lysB) are nonessential.  ...  This work was supported by NIH grant AI-08722 (to R.C.) and by NIH grant GM-34651 and ACS grant MV-566 (to G.E.C.).  ...

DNA sequences of the tail fiber genes of bacteriophage P2: evidence for horizontal transfer of tail fiber genes among unrelated bacteriophages

E Haggård-Ljungquist, C Halling, R Calendar
1992 Journal of Bacteriology  
The similarities in the tail fiber genes of phages of different families provide evidence that illegitimate recombination occurs at previously unappreciated levels and that phages are taking advantage  ...  We have determined the DNA sequence of the bacteriophage P2 tail genes G and H, which code for polypeptides of 175 and 669 residues, respectively.  ...  We thank Edouard Kellenberger, Gail Christie, and Rainer Ziermann for helpful discussions; Erich Six for providing phage; and Mel Sunshine, G.  ...
