Description: <i>Trichoderma reesei</i> cellulase

Fournisseur: MP Biomedicals

Description: Activators: Papain is activated by cysteine, sulphide, sulphite and more. It is enhanced when heavy metal binding agents such as EDTA are also present. N-bromosuccinimide enhances the activity. Inhibitors: Substances which react with sulphydryl groups including heavy metals, carbonyl reagents. Aldehydes are papain inhibitors. Benzoylamidoacetonitrile is an inhibitor. See Shapira and Arnon (1967a and b) on antibody inhibitors. Papain may be inactivated by H₂O₂ generated by γ-irradiation of H₂O⁻ the active SH group being oxidised to sulphenic acid. Specific inhibitors are AEBSF, antipain, cystatin, E-64, leupeptin, PMSF, TLCK and TPCK.

Description: Preparation Method
Produced from 3× crystallised chymotrypsinogen

α-Chymotrypsin is used for treating pancreatic insufficiency and in traumatology.

Chymotrypsin preferentially catalyses the hydrolysis of peptide bonds involving L-isomers of tyrosine, phenylalanine, and tryptophan. It also readily acts upon amides and esters of susceptible amino acids. In addition to bonds involving aromatic amino acids, chymotrypsin catalyses at a high rate the hydrolysis of bonds of leucyl, methionyl, asparaginyl, and glutamyl residues. a-Chymotrypsin is a protein consisting of 241 amino acid residues. The molecule has three peptide chains: an A chain of 13 residues, a B chain of 131 residues, and a C chain of 97 residues.

Description: Pepsin is an acid protease, contains a proteolytic enzyme. It contains the "cathepsin" component which has milk curdling activity. It has a broad range of substrate activity and demonstrates an esterase acitivity. It generally attacks peptide bonds.

Description: Proteinase K is a highly active stable endopeptidase with a broad spectrum of action was isolated by E. Merk's Darmstadt Biochemical Research Department in 1970 from a culture filtrate of the fungus, Tritirachium album Limber. This fungus is able to grow on Keratin (e.g., wool, horn particles) as the sole source of carbon and nitrogen. The isolated protease was, therefore, given the K designation.
Proteinase K is a stable and highly reactive serine protease. Evidence from crystal and molecular structure studies indicates the enzyme belongs to the subtilisin family with an active-site catalytic triad (Asp39-His69-Ser224). It is stable in a broad range of environments: pH, buffer salts, detergents (SDS), and temperature. In the presence of 0,1 to 0,5% SDS, proteinase K retains activity and will digest a variety of proteins and nucleases in DNA preparations without compromising the integrity of the isolated DNA.

Description: Zymolyase-20T is an enzyme preparation from a submerged culture of <i>Arthrobacter luteus</i> which effectively lyses cell walls of viable yeast cells. The primary enzyme in this preparation responsible for lysis of viable yeast cells is ß-1,3-glucan laminaripentaohydrolase. It hydrolyzes glucose polymers at the ß-1,3-glucan linkages releasing laminaripentaose as the principal product.
