Abstract excerpt

Bacteriophage T4 late promoters, which consist of a simple 8-base pair TATA box, are recognized by the gene 55 protein (gp55), a small, highly diverged member of the sigma family proteins that replaces sigma(70) during the final phase of the T4 multiplication cycle. A 16-amino acid segment of gp55 that is proposed to be homologous to the sigma(70) region 2.2 has been subjected to alanine scanning and other...
