Ubiquitin C-terminal hydrolases (UCH) are deubiquitinating enzymes which hydrolyze esters and amides of ubiquitin. Here we report the processing a number ubiquitin derivatives by two human UCH isozymes (isozymes L1 L3) find that these show little discrimination based on P1' amino acid, except proline is cleaved slowly. Ubiquitinyllysine linked α- or ε-amino group hydrolyzed at identical rates. Isozyme-specific hydrolytic preferences only evident when leaving large. The gene products can be...

Ubiquitin C-terminal hydrolases (UCH's) are a newly-defined class of thiol proteases implicated in the proteolytic processing polymeric ubiquitin. They important for generation monomeric ubiquitin, active component eukaryotic ubiquitin-dependent system. There at least three mammalian isozymes which tissue specific and developmentally regulated. To study structure functional roles these highly homologous enzymes, we have subcloned overexpressed two isozymes, UCH-L1 UCH-L3. Here, report their...

Enterovirus D68 (EV-D68) caused a severe respiratory illness outbreak in the United States 2014. Reports of acute flaccid myelitis (AFM)/paralysis (AFP) several independent epidemiological clusters children with detectable EV-D68 have raised concerns that genetic changes could be causing increased disease severity and neurological symptoms.

The rapid spread of Zika virus (ZIKV) has caused much concern in the global health community, due part to a link fetal microcephaly and other neurological illnesses. While an increasing amount ZIKV genomic sequence data is being generated, understanding molecular biology still greatly lacking. A significant step towards establishing proteomics would be compilation all proteins produced by virus, resultant genotypes. Here we report for first time such data, using new computational methods...

The ubiquitin superfamily is a rich repository of small, conserved, functionally unique, and important proteins. Its member proteins fold simply similarly, with kinetic thermodynamic ease (Sorenson, J. M.; Head-Gordon, T. Toward minimalist models larger proteins: A ubiquitin-like protein. Proteins 2002, 46, 368-379). They have been implicated in numerous cancers, neurodegenerations, inflammations, various disorders affecting signal transduction or protein half-life. These serve the cell...
