Cloning and molecular analysis of the galE gene of Neisseria meningitidls and its role in lipopolysaccharide biosynthesis.

The galE gene from Haemophilus influenzae was used as a hybridization probe for the galE gene of Neisseria meningitidis Group B, identifying two different homologous loci. Each of the loci was cloned and nucleotide sequence analysis revealed that both loci contained sequences similar to galE. One contained a functional galE gene and mapped to the capsule biosynthetic locus.
