New data from N. Ranjit et al illuminate research in hookworm disease
April 8th, 2009
According to recent research from Brisbane, Australia, "Blood-feeding parasites use mechanistically distinct proteases to digest hemoglobin (Hb), often as multienzyme cooperative cascades. We investigated the roles played by 3 distinct proteases from adults of the human hookworm Necator americanus." "The aspartic protease Na-APR-1 and the cysteine protease Na-CP-3 were expressed in catalytically active form in yeast, and the metalloprotease Na-MEP-1 was expressed in catalytically active form in baculovirus. Antibodies to all 3 proteases were used to immunolocalize each native enzyme to the intestine of adult N. americanus. Recombinant Na-APR-1 cleaved intact human Hb....
