• HOIP s ability to build linear Ub chains arises

  2020-09-18

  

  HOIP\'s ability to build linear Ub chains arises from a unique domain that follows directly after the RING2 domain, the linear ubiquitin chain-determining domain (LDD) (Fig. 1). Structures have revealed that the LDD is structurally integrated into RING2, creating a single RING2–LDD unit (Fig. 2D) [4

  2020-09-18

  

  Crystallographic and NMR-based analyses have revealed that RINGs and U-boxes have a common mode of interaction with E2s (Fig. 2A). The key structural elements are two loop-like regions, which, in the case of RINGs, coordinate Zn. The loops surround a shallow groove formed by the central α-helix. Tog

  2020-09-18

  

  Ubiquitination is a reversible posttranslational modification. The removal of Ub is carried out by enzymes known as deubiquitinases (DUBs). The antagonistic role played by these enzymes in the Ub pathway regulates the function of the ubiquitinated proteins, while maintaining the free Ub pool in euka

  2020-09-18

  

  To explore the mechanism behind differential activation kinetics, Marcott et al. (2018) manipulate local dopamine dynamics. They show that differences in dopamine concentrations are not responsible for different D2R activation kinetics, since D2-IPSCs reach similar amplitudes at different rates in N

  2020-09-18

  

  Our finding that one enzyme acts both as a primase and a DNAP poses evolutionary and mechanistic questions. In particular, why do cellular organisms require two enzymes to fulfill de novo DNA synthesis? The inability of cellular replicases to perform as primases might be dictated by the challenges a

  2020-09-18

  

  One step in pyrimidine biosynthesis is conversion of l-dihydroorotate (DHO) to orotate (ORO), under action of the enzyme dihydroorotate dehydrogenase (DHODH, EC 1.3.99.11), which contains a flavine (FMN) as redox cofactor [1]. In this transformation, electrons resulting from DHO oxidation are transf

  Indeed, a significant difference was observed for the binding of glycated α-synuclein. Thus, g-α-synuclein bound to other part of GAPDH in 4 of 10 simulations (Fig. 2F, brown, yellow and dark-green chains, and Fig. 2G, brown chain). This additional binding site is located on the interface between O

  In the present study, we combined activity-based protein profiling, biochemical and genetic approaches to identify the PLCPs involved in the sphingolipid pathway leading to plant PCD. By using Arabidopsis Vidofludimus and leaves, we demonstrate that this sub-class of plant proteases is activated in

  Funding sources Introduction Psychiatric comorbidities affect up to 70% of people with pharmacoresistant epilepsy and significantly impact quality of life [1]. Psychiatric comorbidities in epilepsy have been thought to be due to psychosocial stress. However, recent evidence suggests a more com

  Acknowledgements Introduction α-L-Rhamnosidases (EC 3.2.1.40) are glycosyl hydrolases (GHs) that cleave terminal α-l-rhamnose from a large number of natural products [1]. The action of α-L-rhamnosidases (α-RHAs) has been reported, among others, on different complex substrates such as heteropol

  EphB4 promotes tumor growth by stimulating angiogenesis through EphrinB2 [18]. However, the distinct and specifically involvement of Isorhamnetin sale and veins in the tumor angiogenesis of all tumor grades is unclear. Our results indicate that the relation between EphrinB2 and EphB4 stained blood v
