Identification and characterization of burkholderia pseudomallei K96243 serine and metallopeptidase

Burkholderia pseudomallei K96243, the causative agent of melioidosis, is reported to produce various extracellular products, including proteases. The role of these proteases in the melioidosis, however, remains obscure. Previous findings have hinted at the inherent pathogenicity of the protease duri...
