Deoxyribonuclease from beef pancreas, DNase I, was first crystallized by Kunitz. It is an endonuclease which splits phosphodiester linkages, preferentially adjacent to a pyrimidine nucleotide yielding 5'-phosphate terminated polynucleotides with a free hydroxyl group on position 3'. The average chain of limit digest is a tetranucleotide. DNase I acts upon single chain DNA, and upon double-stranded DNA and chromatin.

Streptokinase catalyzes hydrolysis of amide linkages. Forms a 1:1 complex with plasminogen which is then converted to streptokinase-plasmin. Both streptokinase-plasminogen and streptokinase-plasmin complexes can activate plasminogen. As a result of its interaction with human or rabbit plasminogen, streptokinase undergoes specific fragmentation.

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.

Supplier: MP Biomedicals

Suitable for both protein and nucleic acid isolation. Exhibits proteolytic activity on proteins, peptides, glycoproteins, amides and esters. Also active with nitroanilides of amino acids with protected amino groups, excluding arginine. Useful in the isolation of DNA and RNA, in the analysis of membrane structures and protein structure. Proteolytic activity: >30mAnson Units/mg Unit definition: One Anson unit is the amount of enzyme which liberates 1 µmol of Folin-positive amino acids per minute at pH 7,5 and 35 °C, using hemoglobin as substrate.
