Human liver cathepsin L.
Cathepsin L was purified to apparent homogeneity from human liver obtained post mortem. It was necessary to treat the homogenate at pH 4.2 and 37 degrees C to release active enzyme. The purification procedure involved ion-exchange chromatography on carboxymethyl-Sephadex and the Mono S column of a Pharmacia fast-protein-liquid-chromatography system. The enzyme was found to consist of two polype...
متن کاملHuman cathepsin D.
A literature survey was performed of human cathepsin D gene, cathepsin D biosynthesis, posttranslatory modifications, transport within the cell, substrate specificity and catalytic effect. Methods used to determine the activity and level of this proteinase as well as its role in the biochemistry and pathobiochemistry of cells, tissues and organs were considered.
متن کاملCathepsin E (EC 3.4.23.34)--a review.
Cathepsin E belongs to the third class of enzymes - hydrolases, a subclass of peptide bond hydrolases and a sub-subclass of endopeptidases with aspartic catalytic sites. Cathepsin E is an endopeptidase with substrate specificity similar to that of cathepsin D. In a human organism, cathepsin E occurs in: erythrocytes, thymus, dendritic cells, epithelial M cells, microglia cells, Langerhans cells...
متن کاملHuman gastric cathepsin E. Predicted sequence, localization to chromosome 1, and sequence homology with other aspartic proteinases.
The predicted sequence of human gastric cathepsin E (CTSE) was determined by analysis of cDNA clones isolated from a library constructed with poly(A+) RNA from a gastric adenocarcinoma cell line. The CTSE cDNA clones were identified using a set of complementary 18-base oligonucleotide probes specific for a 6-residue sequence surrounding the first active site of all previously characterized huma...
متن کاملCathepsin E Deficiency Ameliorates Graft-versus-Host Disease and Modifies Dendritic Cell Motility
Microbial products influence immunity after allogeneic hematopoietic stem cell transplantation (allo-SCT). In this context, the role of cathepsin E (Ctse), an aspartate protease known to cleave bacterial peptides for antigen presentation in dendritic cells (DCs), has not been studied. During experimental acute graft-versus-host disease (GVHD), we found infiltration by Ctse-positive immune cells...
