| | Resumo: | A novel Mycobacterium leprae lipoprotein LpK (accession no. ML0603) was identified from the genomic database. The 1,116-bp open reading frame encodes a 371-amino-acid precursor protein with an N-terminal signal sequence and a consensus motif for lipid conjugation. Expression of the protein, LpK, in Escherichia coli revealed a 33-kDa protein, and metabolic labeling experiments and globomycin treatment proved that the protein was lipidated. Fractionation of M. leprae demonstrated that this lipoprotein was a membrane protein of M. leprae. The purified lipoprotein was found to induce production of interleukin-12 in human peripheral blood monocytes. The studies imply that M. leprae LpK is involved in protective immunity against leprosy and may be a candidate for vaccine design. (AU).
