title: Cloning and analysis of the gene for the major outer membrane lipoprotein from Pseudomonas aeruginosa.
abstract: The gene for the Pseudomonas aeruginosa outer membrane lipoprotein I was isolated from a genomic library in the phage lambda EMBL3 vector and subsequently subcloned in the low copy-number, wide host-range plasmid vector, pKT240. The cloned gene was highly expressed, resulting in the production of a low molecular-weight protein (8 kD) that was found to be associated with the outer membrane. Sequence analysis showed an open reading frame of 83 amino acids with a putative N-terminal hydrophobic signal peptide of 19 residues immediately followed by the lipoprotein consensus sequence, GLY-CYS-SER-SER (residues 19-22). The predicted amino acid composition of the mature polypeptide and that of the purified lipoprotein I of P. aeruginosa (Mizuno and Kageyama, 1979) were identical. In contrast with other Gram-negative outer membrane lipoproteins, conformation predictions suggested that the mature protein was a single alpha helix.
