Abstract

A homolog of the meningococcal cps locus region E has been identified in Neisseria gonorrhoeae immediately upstream of the gonococcal region D locus. Region E has no detectable function in capsule biosynthesis in Neisseria meningitidis or in lipopolysaccharide biosynthesis in either organism. The open reading frame is homologous to proteins of unknown function in Escherichia coli and Haemophilus influenzae. Further analysis of the N. meningitidis cps cluster has identified a second copy of region D encoding three additional open reading frames, including homologs of DNA methyltransferases. The organization of the region D and E genes in N. gonorrhoeae and N. meningitidis in relation to the cps genes provides some insight into the evolutionary origin of encapsulation in N. meningitidis
