...Clara L. Frazier; Amy M. Weeks Enzymes that catalyze peptide ligation are powerful tools for site-specific protein bioconjugation and the study of cellular signaling. Peptide ligases can be divided into two classes: proteases that have been engineered to favor peptide ligation, and protease-related...

...Derek Wilkinson; Mark Ramsdale A variety of proteases have been implicated in yeast PCD (programmed cell death) including the metacaspase Mca1 and the separase Esp1, the HtrA-like serine protease Nma111, the cathepsin-like serine carboxypeptideases and a range of vacuolar proteases. Proteasomal...

.... proteolysis, unfolding, disaggregation and disassembly. In the oligomeric ring of the AAA protein, there is a conserved aromatic residue which lines the central pore. Functional analysis indicates that this conserved residue in AAA proteases is involved in threading unfolded polypeptides. Katanin and spastin...

...C. Southan Multiple alignments and phylogenetic tree constructions are established techniques for examining the evolutionary history of protease sequences in organisms such as humans, mice, fruitflies, nematode worms and yeast. They also facilitate the mapping of those conserved positions...

...K.L. Moffitt; S.L. Martin; B. Walker Unregulated apoptosis can be due to a disruption in the balance and control of both intra- and inter-cellular proteolytic activities leading to various disease states. Many proteases involved in apoptotic processes are yet to be identified; however, several...

... or cancer. The completion of the human genome sequence allowed us to determine that more than 2% of all human genes are proteases or protease inhibitors, reflecting the importance of proteolysis in human biology. To understand better the complexity of proteases in human and other model organisms, we have...

...A. Amour; M. Bird; L. Chaudry; J. Deadman; D. Hayes; C. Kay Proteases are involved in the regulation of a wide variety of essential physiological processes, often by participating in a highly orchestrated sequence of events termed a ‘proteolytic cascade’. Four major proteolytic cascades...

... proteases (MASPs) attached to MBL, and MASP-2 activates complement proteins C4 and C2. The MASPs are homologous to the C1q-associated proteases, C1r and C1s. MBL therefore activates complement by a mechanism very similar to C1q, and engages the opsonic activity of complement to clear micro-organisms...

...E. M. Creagh; S. J. Martin Apoptosis is co-ordinated by a family of cysteine proteases, the caspases, that dismantle the cell by targeting a panoply of proteins for limited proteolysis. The mammalian caspase family contains 14 members, a subset of which participates in apoptosis, with the remainder...

... of the components involved in these functions, such as translocons, chaperones and proteases, have been identified but many of the auxiliary functions of photosynthesis remain uncharacterized.
