The amino acid sequences of mammalian protein phosphatase 1 and 2A were compared pairwise with every sequence in the National Biomedical Research Foundation protein sequence database using an exhaustive searching programme [Coulson et al., Comp. J. 30 (1987) 420-424]. The N-terminal half of the protein encoded by an open reading frame, orf 221, in bacteriophage lambda (nt 43,224-43,886 in the map of Daniels et al. [in Hendrix et al. (Eds.), Lambda II. Cold Spring Harbor Laboratory, Cold Spring Harbor, NY, 1983, pp. 519-676] shows 35% identity to either protein phosphatase 1 or 2A in this region. If conservative replacements are included the overall homology rises to 49%. A gene in phi 80 also shows 35% identity with the mammalian protein phosphatases. The results indicate that orf 221 of phage lambda and the homologous phi 80 gene may encode protein phosphatases. The possible roles of protein phosphorylation in the propagation of bacteriophage are discussed.
