title: A secondary attachment site for bacteriophage lambda in trpC of E. coli.
abstract: We have determined the nucleotide sequence of a secondary lambda attachment site in trpC. Direct sequence analysis of lambdatrp transducing phage DNA fragments carrying the two prophage attachment sites reveals a 6 nucleotide homology in the crossover region which is a subset of the 15 nucleotide core sequence in the primary lambda attachment site: GCTTTTTTATACTAA. This 6 nucleotide sequence is also present in the intact trpC genome at the attachment site, as shown by analysis of trpC mRNA spanning this region.
