Abstract

We have cloned DNA methyltransferases (MTases) from various strains of Neisseria gonorrhoeae. Each of these clones represents a single specificity, indicating that the multiple gonococcal MTase specificities are encoded by monospecific MTases. The DNAs of five strains (FA5100, F62, MS11, Pgh3-2, and WR302) were digested with NheI, SpeI, or NheI plus SpeI and subjected to pulsed-field gel electrophoresis. The DNA MTase clones were used to probe Southern blots of these pulsed-field gels to determine whether the MTase genes are linked and whether there are strain-to-strain differences. The results indicate that none of these genes are closely linked, but variable hybridization patterns indicate that there exist restriction fragment length polymorphisms between the strains tested. Most of the chromosomal regions containing these restriction fragment length polymorphisms are clustered in regions containing gonococcal genes known or suspected to antigenically vary via genetic recombination.
