Porcine spleen cathepsin B is an exopeptidase.
The major cathepsin B isozyme CB-I purified from porcine spleens was studied for its specificity against various peptide and denatured protein substrates. The enzyme degraded all the peptide substrates by an exopeptidase activity. The substrates were degraded mainly by a dipeptidyl carboxypeptidase activity of the enzyme except for angiotensin I, from which a COOH-terminal leucine residue was r...
متن کاملModeling Exopeptidase Activity from LC-MS Data
Recent studies demonstrate that the peptides in the serum of cancer patients that are generated (ex vivo) as a result of tumor protease activity can be used for the detection and classification of cancer. In this paper, we propose the first formal approach to modeling exopeptidase activity from liquid chromatography-mass spectrometry (LC-MS) samples. We design a statistical model of peptidome d...
متن کاملIdentification of lactobacilli and bifidobacteria.
Selective culture media and phenotypic tests enable lactobacilli to be differentiated from morphologically similar bacteria. The accurate identification of Lactobacillus species can be accomplished by reference to 16S rRNA gene sequences. Species-specific, PCR primers that target the 16S-23S rRNA spacer region are available for a limited number of Lactobacillus species. Molecular methods for th...
متن کاملComparison of Bifidobacteria Selective Media for the Detection of Bifidobacteria in Korean Commercial Fermented Milk Products
This study was carried out to compare the efficacy and selectivity of TOS and BS media for enumeration of bifidobacteria in commercial fermented milk products. First, bifidobacteria was isolated from 20 fermented milk products, and all isolated bifidobacteria were identified by genomic technology as Bifidobacterium lactis. The two media significantly differed from each other with regard to the ...
متن کاملInfluence of Maternal Bifidobacteria on the Development of Gut Bifidobacteria in Infants
Intestinal microbiota plays an important role in human health by influencing metabolic activities that result in the creation of energy and absorbable nutrients, a barrier to the colonization of pathogens, and stimulation of the immune system. The development of fecal microbiota in neonates is crucial because those bacteria are the first to colonize the sterile intestine of the neonates and, th...
