Cloning, sequence and in vitro transcription/translation analysis of a 3.2-kb EcoRI-HindIII fragment of Leuconostoc oenos bacteriophage L10.

A 3.2-kb EcoRI-HindIII DNA fragment of Leuconostoc oenos bacteriophage L10 was cloned and sequenced. Computer-assisted analysis of the sequence identified eleven possible open reading frames (ORFs) that were all on the same strand. In vitro transcription/translation analysis of the full-length DNA fragment yielded five prominent proteins that were correlated with ORFs by their sizes and expression from deleted clones. Only those ORFs containing recognizable Shine-Dalgarno sequences coded for proteins. Neither the nucleotide sequence, nor deduced amino-acid sequences showed significant homology with other known sequences.
