Ploegh1,* 1Whitehead Institute for Biomedical Research, Cambridge, MA 02142, USA *Correspondence: [email protected] DOI 10.1016/j.chom.2009.05.012 Ubiquitin is important for nearly every aspect of cellular physiology. All viruses rely extensively on host machinery for replication; therefore, it is not surprising that viruses connect to the ubiquitin pathway at many levels. Viral involvement with ubiquitin occurs either adventitiously because of the unavoidable usur- pation of cellular processes, or for some specific purpose selected for by the virus to enhance viral replica- tion. Here, we review current knowledge of how the ubiquitin pathway alters viral replication and how viruses influence the ubiquitin pathway to enhance their own replication. Introduction own ubiquitin ligases or ubiquitin-specific proteases, it seems Ubiquitin is a small 76 amino acid protein widely expressed in reasonable to infer functional relevance, but even in these cases, eukaryotic cells. -

In the present study, we affinity-purified the binding benzyloxycarbonyl-L-lysine thiobenzyl ester (BLT), and the BLT protein from the 2 % (w/v) Triton X-100-soluble fraction of hydrolysis was inhibited by PSTI.

Group A streptococci (GAS) and Staphylococcus aureus are two major pathogens associated with monomicrobial NSTIs. In the tissue environment, both Gram-positive bacteria secrete a variety of molecules, including pore-forming exotoxins, superantigens, and proteases with cytolytic and immunomodulatory functions. The present review summarizes the current knowledge about streptococcal and staphylococcal toxins in NSTIs with a special focus on their contribution to disease progression, tissue pathology, and immune evasion strategies. Keywords: Streptococcus pyogenes; group A streptococcus; Staphylococcus aureus; skin infections; necrotizing soft tissue infections; pore-forming toxins; superantigens; immunomodulatory proteases; immune responses Key Contribution: Group A streptococcal and Staphylococcus aureus toxins manipulate host physiological and immunological responses to promote disease severity and progression. 1. Introduction Necrotizing soft tissue infections (NSTIs) are rare and represent a more severe rapidly progressing form of soft tissue infections that account for significant morbidity and mortality [1]. -

Tests are performed on rabbit meat samples treated with papain and two vegetal sources of natural proteases (extracts of kiwifruit and ginger root). Two variants of marinade solutions are prepared from each vegetable raw materials– 50% (w/w) and 100 % (w/w), with a duration of processing 2h, 24h, and 48h. Changes in the following physico- chemical characteristics of meat have been observed: pH, water-holding capacity, cooking losses and quantity of free amino acids. Differences in values of these characteristics have been observed, both between control and test samples, as well as depending of treatment duration. For meat samples marinated with papain and ginger extracts, the water-holding capacity reached to 6.74 ± 0.04 % (papain), 5.58 ± 0.09 % (variant 1) and 6.80 ± 0.11 % (variant 2) after 48 hours treatment. In rabbit meat marinated with kiwifruit extracts, a significant increase in WHC was observed at 48 hours, 3.37 ± 0.07 (variant 3) and 6.84 ± 0.11 (variant 4). -

Box 9600, 2300 RC Leiden, Netherlands2 Received 27 April 2010/Accepted 15 July 2010 Coronaviruses encode two classes of cysteine proteases, which have narrow substrate specificities and either a chymotrypsin- or papain-like fold. These enzymes mediate the processing of the two precursor polyproteins of the viral replicase and are also thought to modulate host cell functions to facilitate infection. The papain-like protease 1 (PL1pro) domain is present in nonstructural protein 3 (nsp3) of alphacoronaviruses and subgroup 2a betacoronaviruses. It participates in the proteolytic processing of the N-terminal region of the replicase polyproteins in a manner that varies among different coronaviruses and remains poorly understood. Here we report the first structural and biochemical characterization of a purified coronavirus PL1pro domain, that of transmissible gastroenteritis virus (TGEV). Its tertiary structure is compared with that of severe acute respiratory syndrome (SARS) coronavirus PL2pro, a downstream paralog that is conserved in the nsp3’s of all coronaviruses.
