Nucleotide sequence changes associated with mutation of the prm promoter of bacteriophage λ have been determined. Prm mutations have been assigned to two classes. Class I mutations appear to affect the interaction of RNA polymerase with prm ;six class I mutations affect four sites, located 14, 33, 38, and 39 bp preceding the prm transcription startpoint. Class II mutations appear to owe their Prm phenotype to a change in oR, which could prevent activation of prm by repressor. All three class II mutations are in oR 1.
