Abstract

The nucleoid-associated 'histone-like protein I' (HLP-I) protein of E. coli was found to be homologous with the cationic 16-kDa outer membrane protein OmpH of Salmonella typhimurium. Deduced from the nucleotide sequence, the HLP-I protein has 91% identical residues with the OmpH protein. Both proteins have very similar cleavable signal sequences. The nucleotide sequence similarity between the corresponding genes hlpA and ompH is 87%. The ompH gene is located in a gene cluster resembling the hlpA-ORF17 region of E. coli which is close to the Ipx genes involved in the biosynthesis of lipopolysaccharides. The localization of the OmpH/HLP-I protein in the cell is discussed.
