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.

Aldolase is a tetrameric protein. It catalyses a key reaction in glycolysis and energy production:D-Fructose 1,6-bisphosphate aldolase → dihydroxyacetone phosphate + D-glyceraldehyde-3-phosphate. Aldolase is present in all animal tissue and in most microorganisms. There are two classes of aldolases. Class I aldolase is found in animal and higher plant tissue. Class II aldolase is found in primitrive cells such as yeasts and bacteria. Class I aldolase is characterised by not requiring a bivalent metal cofactor and the formation of a ketimine Schiff base intermediate with the substrate dihydroxyacetone phosphate. Class II aldolase requires a metal cofactor and is inhibited by EDTA. Three types of aldolase exist in animal tissue. The major form, type A is found in muscle; type B is found in liver tissue and type C (plus some type A) is found in brain tissue. Aldolase forms five isozymes which may to various degrees be organ specific.

Factor XIa is a serine protease which participates in the instrinsic pathway of coagulation by catalysing the conversion of factor IX to factor IXa.

Proteolysed forms of α-thrombin have been termed β-thrombin and γ-thrombin. β-thrombin is generated by cleavage of the A-chain of α-thrombin at Arg-13 and Lys-30, and cleavage of the B-chain at Lys-114 and Arg-122. γ-thrombin is generated from β-thrombin by an additional cleavage of the B-chain.

Alpha-thrombin is a highly specific serine protease. During coagulation, thrombin cleaves fibrinogen to form fibrin leading to the formation of a fibrin clot. Thrombin is also responsible for feedback activation of the procofactors factor V and factor VIII. Thrombin has also been reported to activate factor VIII and platelets, and also functions as a vasoconstrictor protein.

DENARASE High Salt is an engineered version of the wild-type Serratia marcescens endonuclease, which is commonly used for DNA removal applications in bioprocessing. Compared to the wild-type DENARASE, a few amino acids were substituted to provide the enzyme with an improved salt tolerance without losing its specificity for nucleic acids.
