Abstract
Lysogenic conversion caused by lambdoid bacteriophage phi80 and that caused by coliphage N15 have similar characteristics, suggesting that similarities in their cor genes and Cor proteins are responsible for this effect. Here we present the nucleotide sequence of the N15 cor gene. The N15 cor gene homolog was found in the phi80 cor region, but in the opposite direction of that of the open reading frame to which the phi80 cor gene had previously been assigned (M. Matsumoto, N. Ichikawa, S. Tanaka, T. Morita, and A. Matsushiro, Jpn. J. Genet. 60:475-483, 1985).
