  Intriguingly, one E2 residue may serve as a molecular ‘gate’ to allow the C-terminus of ubiquitin to access the closed E2~Ub conformations favorable for ubiquitin transfer. This residue, Asp87 in UbcH5 family members, resides on one side of the opening that leads to the active site Cys (Fig. 4D). In

  2019-08-06

  

  Based on the similar activities of Rad6p and Cdc34p (i.e., both are E2 ub-conjugating enzymes) on ubiquitinylation of p33 replication protein, we propose that Rad6p and the plant Ubc2p mono- and bi-ubiquitinate the viral replication proteins in order to facilitate the recruitment of the cellular ESC

  The findings of Qiu et al. (2016) represent the first instance of a Ub-specific mono-ADP-ribosyltransferase, as well as the first documentation of E1/E2 independent ubiquitination. Post-translational modification of Ub certainly adds layers of complexity to our understanding of the Ub signal and sho

  Eggs have been recognized as an important contributor of functional ingredients for humans [3]. Egg yolk is composed of various biologically active proteins. The water-soluble proteins of egg yolk have been examined for their functional effects on longitudinal bone growth during the growth period in

  To ascertain separation of the distinct enzymatic activities found in this protein preparation following separation on the HAP column, a rigorous quantitative analysis was conducted on the nickel–agarose elution and HAP FT pools of protein. For these analyses, each pool of protein was dialyzed in th

  Loss of Chk 1 sensitizes 22 to hypoxia/reoxygenation In contrast to Chk 2, studies have identified Chk 1 as being phosphorylated in an ATR-dependent manner at residue serine 345 during hypoxia [18]. More recently, siRNA mediated inhibition of Chk 1 signaling was found to sensitize cells exposed

  Another milestone in the field is the de novo discovery of EPAC2 and EPAC1 specific inhibitors through fluorescence-based HTS assays. Due to the excellent EPAC/PKA selectivity of fumonisin in , it has been widely applied as a useful chemical probe to discriminate EPAC related signaling pathways and

  The different serotypes (A-G) have unique receptors to which they bind to produce the toxic effect on the nerve cells. (Lance, 2004, Rosetto et al., 2014). Intracellularly, the endopeptidase activity of different serotypes of BoNT target selectively a unique group of proteins, the SNARE Fmoc-Glu(OtB

  The ubiquitin-like modifier NEDD8 (NEURAL PRECURSOR CELL EXPRESSED, DEVELOPMENTALLY DOWN-REGULATED 8) uses similar enzymatic machineries for NEDD8 conjugation as ubiquitin (Figure 1) [11, 12, 13, 14]. In plants as well as in other eukaryotes, the number of E3 ligases for NEDD8 and the number of know

  E3 ubiquitin ligases are key players in the ubiquitin-proteasome pathway because they catalyse ubiquitination of substrate proteins.39, 40, 41 As important regulators of cellular ubiquitination, E3 ligases are emerging as attractive drug targets, particularly in cancer.42, 43, 44 However, E3 ligases
