Evolution in the structure and function of aspartic proteases
Aspartic proteases (EC3.4.23) are a group of proteolytic enzymes of the pepsin family that share the same catalytic apparatus and usually function in acid solutions. This latter aspect limits the… Expand
Enzymic characteristics of secreted aspartic proteases of Candida albicans.
Candida yeasts are rarely infectious, but frequently cause life-threatening systemic infections in patients immunocompromised by AIDS or by immunosuppressive therapeutics. The secreted aspartic… Expand

Cardosin A is an abundant aspartic proteinase from pistils of Cynara cardunculus L. whose milk-clotting activity has been exploited for the manufacture of cheese. Here we report the cloning and… Expand
Modification of the Laemmli sodium dodecyl sulfate-polyacrylamide gel electrophoresis procedure to eliminate artifacts on reducing and nonreducing gels.
Proteolytic activation of recombinant pro-memapsin 2 (pro-beta-secretase) studied with new fluorogenic substrates.
Memapsin 2 (beta-secretase), a membrane-anchored aspartic protease, is involved in the cleavage of beta-amyloid precursor protein to form beta-amyloid peptide. The primary structure of memapsin 2… Expand
Purification and properties of cathepsin D from porcine spleen.
Cathepsin D was purified from porcine spleen to near homogeneity as determined by gel electrophoresis. The isolation scheme involved an acid precipitation of tissue extract, DEAE-cellulose and… Expand
Complete amino acid sequence of streptokinase and its homology with serine proteases.
The complete amino acid sequence of streptokinase has been determined by automated Edman degradation of its cyanogen bromide and proteolytic fragments. The protein consists of 415 amino acid… Expand
The crystal structure of bovine bile salt activated lipase: insights into the bile salt activation mechanism.
BACKGROUND The intestinally located pancreatic enzyme, bile salt activated lipase (BAL), possesses unique activities for digesting different kinds of lipids. It also differs from other lipases in a… Expand
Conformational instability of the N‐ and C‐terminal lobes of porcine pepsin in neutral and alkaline solutions

- 1 September 1993
Pepsin contains, in a single chain, two conformationally homologous lobes that are thought to have been evolutionarily derived by gene duplication and fusion. We have demonstrated that the individual… Expand
