Abstract
A rtrp/lac W205 substitution, fused to the late ragion of bacteriophage lambda, provided a convenient assay for phage late gene expression in the presence or absence of lambda pQ. Comparison of lacZ expression from Q + and Q - phages showed that late gene expression was markedly Q-dependent (263-fold difference). A cis/trans comparison of lambda pQ action showed a 180-fold difference in lacZ expression. The results suggest that pQ is only significantly active when supplied in cis to its site of action.This publication has 32 references indexed in Scilit:
