G+C content of regions containing lav homologs, scanned with a sliding window of 100 bp, in 25-bp increments. hi, H. influenzae Int1; nm, N. meningitidis serotype A Z2491; ng, N. gonorrhoeae. The interval on the abscissa corresponds to bp 113 to 5147 of N. gonorrhoeae contig 140 aligned with N. meningitidis serotype A interval 1660274 to 1654800 (which has a deletion within tmk) by creating a 148-bp gap in the N. meningitidis serotype A sequence starting at bp 4033 and the entire Int1 sequence between tmk and holB.
