Recombinant Aprotinin from E. coli

 Product Information

Cat #
MBS-1909
CAS No.
9087-70-1
Enzyme Commission Number
Product Overview
Aprotinin is a competitive inhibitor of serine protease, which can inhibit the activity of trypsin, chymotrypsin and kininogenase. Aprotinin forms stable complexes with proteases to block the active sites of the enzymes. Most of the aprotinin-protease complex is unbound at pH <3.0. Aprotinin and protease are effectively combined equimolarly. Recombinant aprotinin is expressed by recombinant Escherichia coli and obtained by multiple column purifications. The amino acid sequence is completely consistent with that of bovine aprotinin. The recombinant aprotinin has the same enzymatic properties as animal-derived aprotinin. Alternative to animal-derived aprotinin in various biotechnological processes.

 Description

Aprotinin is a monomeric (single-chain) globular polypeptide derived from bovine lung tissue. It has a molecular weight of 6512 and consists of 16 different amino acid types arranged in a chain 58 residues long that folds into a stable, compact tertiary structure of the 'small SS-rich" type, containing 3 disulfides, a twisted β-hairpin and a C-terminal α-helix.
