An Aspartic Endopeptidase is Involved in the Breakdown of Propeptides of Storage Proteins in Protein‐Storage Vacuoles of Plants

open access: closedEuropean Journal of Biochemistry, 1997
To understand the mechanism of the maturation of various proteins in protein‐storage vacuoles, we purified a 48‐kDa aspartic endopeptidase composed of 32‐kDa and 16‐kDa subunits from castor bean. Immunocytochemical and cell fractionation analyses of the endosperm of maturing castor bean seed showed that the aspartic endopeptidase was localized in the ...

Expression, Purification, and Characterization of Aspartic Endopeptidases:PlasmodiumPlasmepsins and “Short” Recombinant Human Pseudocathepsin

open access: closedCurrent Protocols in Protein Science, 2003
AbstractThe unit describes a basic protocols utilized to obtain milligram amounts of enzymatically active, pure recombinantPlasmodiumplasmepsins and "short" human pseudocathepsin D. Specific details for the expression and purification ofPlasmodium falciparumplasmepsin 2 and "short" human pseudocathepsin D in zymogen form are described in this chapter ...

Recombinant Fungal Aspartic Endopeptidases: Insights into Protein Hydrolysis and Combined Effect with Pepsin for Animal Feed Application

open access: closedJournal of Agricultural and Food Chemistry
Protein hydrolysis under acidic conditions can improve the product quality, nutrient availability, and cost efficiency, particularly when neutral or alkaline enzymes are ineffective. Six fungal aspartic endopeptidases (FAPs) were recombinantly expressed as active enzymes in Komagataella phaffi, with peak activity between 30-50 °C and pH 3.0-4.0 ...

Gene Localization of Aspartate Aminotransferase and Endopeptidase Isozymes in Wheat and Rye Using Developmental and Organ‐Specific Patterns

Plant Breeding, 1991
AbstractWheat, rye and wheat‐rye addition lines have been investigated regarding their developmental and organ‐specific isozyme patterns of aspartate amino‐transferase (AAT) and endopeptidase (EP). Evidence is given, that development‐specific isozymes of AAT are encoded by chromosomes 3R and 4R of ‘Imperial’ rye which can be used as biochemical markers
