General description

Cathepsin B (CTSB; EC 3.4.22.1) is a lysosomal cysteine proteinase involved in intracellular degradation and turnover of proteins. It is involved in the proteolytic processing of amyloid precursor protein (APP). Incomplete proteolytic processing of APP is a causative factor in Alzheimer′s disease. CTSB has also been implicated in the invasion and metastasis of certain cancers.

The Cathepsin B Inhibitor Screening Kit is a simple assay for screening potential inhibitors of CTSB. CTSB activity is measured by cleaving a synthetic 7-amino-4-trifluoromethylcoumarin (AFC)-based substrate to yield AFC, a fluorescent product (λex = 400/λem = 505 nm), proportional to the enzymatic activity present.

Suitability

Suitable for the screening of inhibitors of Cathepsin B.

Natural microbial communities are phylogenetically and metabolically diverse. In addition to underexplored organismal groups1, this diversity encompasses a rich discovery potential for ecologically and biotechnologically relevant enzymes and biochemical compounds2,3. However, studying this diversity to identify genomic pathways for the
