  Generally, glycines (and other small residues such as alanine) present in a helical GxxxG-motif that are facing the same side of the helix form a uniform surface that enables direct contact with a second helix. Crystal structures of multipass membrane proteins have demonstrated that GxxxG-motifs are

  RING-type E3s and their substrates There is enormous diversity in substrate ubiquitination and its regulation, as the targets of RING-type E3s are incredibly varied. RING-type E3s are implicated as tumor suppressors, oncogenes, and mediators of endocytosis, and play critical roles in complex mult

  Introduction The dopaminergic system and its projections including both the prefrontal Monastrol (PFC) and striatum are known as being crucial to synaptic plasticity, skill acquisition and higher order functions (e.g., working memory and cognitive control; Matsumoto et al., 2003). Variations in d

  Multi-hierarchical structure of collagen Protein structure is the foundation of protein functions and properties. It is generally accepted that the protein has biological function only when it has tertiary structure or above. Among the identified 28 types of collagen, most is known about type I c

  The intestinal cholesterol CBL0137 hydrochloride receptor markers sitosterol and campesterol to cholesterol levels were significantly lower in Villin-Tgif1 mice compared to wild type mice, irrespective of diet. However, the decrease was less pronounced in Villin-Tgif1 mice fed a chow diet (∼20–30%)

  In contrast, T-bet downregulated the expression of Tfh functional molecules, CD40L, ICOS, and IL-21; accordingly, T-bet overexpression abrogated the helper function of IL-12-stimulated CD4+ T cells. Thus, T-bet seems more involved in the downregulation of the helper functions than in the differentia

  Materials and methods Results Discussion Cysteine proteases are upregulated under oxidative stress and play an important role in the preservation of cellular metabolism (Usui et al., 2007). Cysteine proteases are also important under abiotic stresses for plants to degrade proteins denatured

  To respond to the need for QNAT, commercial assays have been developed on automated systems. The first reagents for CMV and EBV VLs in whole blood were Abbott RealTime kits on the m2000 SP/RT system (Abbott Molecular Inc, Des plaines, USA) (M2000) [4,5] and Artus QS-RGQ kits on the QIAsymphony RGQ s

  The classical ubiquitination pathway Ubiquitination is an enzymatic process that involves the addition of an ubiquitin protein to a substrate that usually becomes inactivated followed by degradation in the proteasome; however, several other functions have also been described. For the discovery of

  It was hypothesized that if modafinil acts primarily via a noradrenergic mechanism, Dbh −/− mice should be non-responsive since they completely lack NE. In contrast, if modafinil acts mainly through DA systems, these mice should be hypersensitive. Modafinil was tested in Dbh −/− mice using both loco

  Introduction Enzymes have higher selectivity, specificity and efficiency than chemical catalysts. Due to their properties and their green chemistry, biocatalysts are widely used in food, textile and pharmaceutical industry [1], [2]. A high efficient biocatalyst for industrial applications must be s

  While we previously demonstrated that TraG is inhibited by specific transglycosylase inhibitors and that enzymatic activity is strongly reduced upon mutation of the potential catalytic core (Arends et al., 2013), the enzymatic mechanism of both domains was not assigned. Here, by mass spectrometry an
