Structural aspects of activation pathways of aspartic protease zymogens and viral 3C protease precursors.
The three-dimensional structures of the inactive protein precursors (zymogens) of the serine, cysteine, aspartic, and metalloprotease classes of proteolytic enzymes are known. Comparisons of these structures with those of the mature, active proteases reveal that, in general, the preformed, active conformations of the residues involved in catalysis are rendered sterically inaccessible to substra...
متن کاملProtease Inhibitors: Emphasizing Functional Aspects of Aspartic Protease Inhibitors
Aspartic proteases are relatively a small group of proteolytic enzymes. Over the last decade, they have received tremendous research interest as potential targets for pharmaceutical intervention as many have been shown to play significant roles in physiological and pathological processes. Despite numerous efforts, however, the only inhibitors for aspartic proteases currently in the market are d...
متن کاملDetermination of aspartic protease gene dosage in the Onchocerca volvulusgenome
Aspartic proteases are a relatively small group of enzymes which express in various nematodes including Onchocerca volvulus. An estimation of the gene copy number corresponding to the OV7A clone, which contains a cDNA insert encoding approximately two-thirds of the entire coding sequence of aspartic protease of O. volvulus, was made by slot blot analysis in a closely related species O. gibsonig...

متن کاملStructural insights into the activation and inhibition of histo-aspartic protease from Plasmodium falciparum.
Histo-aspartic protease (HAP) from Plasmodium falciparum is a promising target for the development of novel antimalarial drugs. The sequence of HAP is highly similar to those of pepsin-like aspartic proteases, but one of the two catalytic aspartates, Asp32, is replaced with histidine. Crystal structures of the truncated zymogen of HAP and of the complex of the mature enzyme with inhibitor KNI-1...
