Identification of putative horizontal gene transfer events. Identification of horizontal gene transfer events in the Neisseria meningitis genome exemplified by (A) SodC(putative horizontal transferred gene [Kroll et al. 1998]) and (B) a conserved hypothetical protein. Nucleotide coordinates indicate the positions of the genes in the genome. Results are of “sliding window” classification using 500-bp windows with 250-bp overlap. Black, unfilled windows were classified as “being of N. meningitis origin,” and solid black windows as “being ofH. influenzae origin.” Haemophilus Uptake Sequences (HmUS) positions are indicated by small arrows. The numbers of perfect matches to the 29-nucleotide consensus are shown in parentheses. BLASTXresults show similar positions in H. influenzae.
