| Thialysine (S-Aminoethyl-L-cysteine hydrochloride) 98+% | The lysine analog, thialysine, has been implicated in the mechanism for the inhibitory effect of the on human acute leukemia Jurkat T cells. When Jurkat T cells were treated with thialysine (0.32-2.5mM), apoptotic cell death along with several biochemical events such as mitochondrial cytochrome c release, caspase-9 activation, caspase-3 activation, degradation of poly (ADP-ribose) polymerase, and DNA fragmentation was induced in a dose- and time-dependent manner. However, these thialysine-induced apoptotic events were significantly abrogated by an ectopic expression of Bcl-xL, which is known to block mitochondrial cytochrome c release. Decylubiquinone, a mitochondrial permeability transition pore inhibitor, also suppressed thialysine-induced apoptotic events.

| calicivirin | Viruses that are members of the Norovirus genus (Caliciviridae family) are a major cause of epidemic acute viral gastroenteritis.

The presence of acidic (Asp), basic (Arg), aromatic (Tyr) or aliphatic (Leu) amino acids at the P1' position results in only minor differences in cleavage efficiency, suggesting that steric or...C-like protease; calicivirus endopeptidase; rabbit hemorrhagic disease virus 3C endopeptidase.
