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.

    Abz-HPGGPQ-EDDnp
    Abz-HPGGPQ-EDDnp (Cathepsin K substrate) is a biological active peptide. (Cathepsins are a class of globular lysosomal proteases, playing a vital role in mammalian cellular turnover. They degrade polypeptides and are distinguished by their substrate specificities. Cathepsin K is the lysosomal cysteine protease involved in bone remodeling and resorption. It has potential as a drug target in autoimmune diseases and osteoporosis.This FRET peptide can be used to monitor selectively cathepsin K activity in physiological fluids and cell lysates. Abz-HPGGPQ-EDDnp [where Abz represents o-aminobenzoic acid and EDDnp represents N -(2, 4-dinitrophenyl)-ethylenediamine], a substrate initially developed for trypanosomal enzymes, is efficiently cleaved at the Gly-Gly bond by cathepsin K. This peptide is resistant to hydrolysis by cathepsins B, F, H, L, S and V, Ex/Em=340 nm/420 nm.)
