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.
