In this paper, we report kinetic studies for the chymotryptic activity of the 20S proteasome. Major observations include the following: (1) Reaction progress curves that are recorded at concentrations of Suc-Leu-Leu-Val-Tyr-AMC greater than about 40 microM are biphasic and characterized

We have purified two high molecular weight proteases approximately 400-fold from rabbit reticulocyte lysate. Both enzymes hydrolyze 125I-alpha-casein and 4-methylcoumaryl-7-amide peptides with tyrosine, phenylalanine, or arginine at the P1 position. Both are inhibited by hemin, thiol reagents, chymostatin, and leupeptin.

Excess lipid accumulation resulting from an elevated supply of plasma fatty acids is linked to the pathogenesis of the metabolic syndrome and heart disease. The term 'lipotoxicity' was coined to describe how lipid accumulation leads to cellular dysfunction and death
