Alterations of the portal protein, gpB, of bacteriophage lambda suppress mutations in cosQ, the site required for termination of DNA packaging.

Genetics - 1 May 2002

Wieczorek Douglas J, Didion Lisa, Feiss Michael

Abstract excerpt

The cosQ site of bacteriophage lambda is required for DNA packaging termination. Previous studies have shown that cosQ mutations can be suppressed in three ways: by a local suppressor within cosQ, an increase in the length of the lambda chromosome, and missense mutations affecting the prohead's portal protein, gpB. In the present work, revertants of a set of lethal cosQ mutants were screened for suppressors....
