Activating Compound

EC Number Activating Compound Comment Organism Structure
3.4.25.2 HslU HslV can slowly hydrolyze insulin B-chain, casein or carboxymethylated lactalbumin, but its activity is stimulated 20fold by HslU in presence of ATP Escherichia coli

Inhibitors

EC Number Inhibitors Comment Organism Structure
3.4.25.2 benzyloxycarbonyl-Ile-Glu(tert-butyl)-Ala-Leu-al 0.001 mM, almost complete inhibition of peptidase activity, no inhibition of hydrolysis of insulin B-chain or other polypeptide substrates Escherichia coli
3.4.25.2 benzyloxycarbonyl-Leu-Leu-norvalinal 0.004 mM, inhibits hydrolysis of both benzyloxycarbonyl-GGL-7-amido-4-methylcoumarin and insulin B-chain to a similar extent Escherichia coli
3.4.25.2 lactacystin irreversible, much greater inhibition of the degradation of insulin B-chain than on peptide hydrolysis Escherichia coli
