Ser/Thr Protease

Serine proteases; Serine endopeptidases; Threonine proteases

Serine (Ser) proteases catalyse the hydrolysis of specific peptide bonds in their substrates and this activity depends on a set of amino acids in the active site of the enzyme, one of which is always a serine. There are two families especially well studied, the trypsin family and the subtilisin family. Serine proteases play crucial roles in a wide variety of cellular as well as extracellular functions, including the process of blood clotting, protein digestion, cell signaling, inflammation, and protein processing. Threonine (Thr) proteases are a family of proteolytic enzymes harbouring a threonine residue within the active site. The prototype members of this class of enzymes are the catalytic subunits of the proteasome, however the acyltransferases convergently evolved the same active site geometry and mechanism.

    Benzamidine
    Inhibitor
    Benzamidine is a competitive protease inhibitor that blocks the hydrolytic cleavage of glucagon by plasmin, trypsin and thrombin. Benzamidine effectively inhibits the degradation of glucagon by relevant proteases during the collection, storage and analysis of human plasma and blood samples. During in vivo metabolism, Benzamidine undergoes N-hydroxylation and produces multiple metabolites, exhibiting characteristics of delayed excretion or biphasic elimination. Benzamidine only induces slight single-strand DNA breaks at high concentrations and shows no significant genotoxic potential overall. Benzamidine may interfere with the detection of some glucagon antisera, but does not affect key antigen-antibody affinity at specific concentrations. Benzamidine can be used as a stabilizer in glucagon radioimmunoassays to ensure the accuracy and recovery rate of detection results.
