RL Unpublished (1988).
RL U.S. Patent No. 4,774,182 dated Sept. 27, 1988.
CC This was isolated as spontaneous mutant of lambda papa prophage. It
CC contains an IS2 terminator between the tR1 site and the O gene.
CC This replicates in sup hosts (clear plaques at 42C; turbid plaques at
CC 30C). It does not grow on sup0 hosts and does not kill a sup0 host
CC when lysogenized and induced at 42C. (personal communication)
CC This is bacteriophage lambda with mutant O and P genes regulated by
CC the N product (functional only when N is supplied). It produces
CC immunity to lambda.
