Correlation between PT sequence contexts and Dnd protein sequences. Phylogenetic analysis reveals a correlation between PT sequence context and four of the Dnd protein sequences, and supports horizontal rather than vertical gene transfer for dnd genes. Dnd protein sequences for 12 strains analyzed here were retrieved from the NCBI Protein database and aligned using Muscle (35) and phylogenetic trees were computed with phyML (36), with phylogenies displayed using iTol (37). The PT sequence context is color-coded as noted in the key.
