The complete amino acid and nucleotide sequence of a secreted metalloprotease produced by Actinobacillus pleuropneumoniae serotype 1 is reported. A clone showing proteolytic activity in cell-free culture media was selected from a genomic library of A. pleuropneumoniae serotype 1 in pUC 19. The sequence obtained contained an open reading frame encoding a protein with 869 amino acids. This protein was identified as a zinc neutral-metalloprotease belonging to the aminopeptidase family, with a predicted molecular weight of approximately 101 kDa. This sequence showed high homology with other predicted or sequenced aminopeptidases reported for different Gram-negative bacteria. Expression of the protease was observed in lung tissue from pigs that died of porcine pleuropneumonia suggesting a role in pathogenesis. © 2004 Federation of European Microbiological Societies.
