title: Nucleotide sequence and genome organisation of filamentous bacteriophages fl and fd.
abstract: The DNA sequence of the filamentous phage F1, consisting of 6407 nucleotides, has been determined. When compared with the DNA sequence of the related filamentous phage fd (Beck et al., 1978), the f1 sequence is one nucleotide shorter and differs in 180 positions from the fd DNA. Only ten of these base exchanges cause amino acid exchanges in the known gene products. Most of the exchanges in f1 are the same as in M13 (Van Wezenbeek et al., 1980), showing a near identity of these two phage (there are only 59 nucleotide differences). Regulatory units for replication, transcription, and translation are in their essential parts identical in all three phage.
