  Introduction Protein ubiquitination is a posttranslational modification that plays a major role in almost all cellular processes in eukaryotes (Hochstrasser, 2009; Komander & Rape, 2012). It involves the covalent attachment of ubiquitin (Ub) via its C-terminal glycine carboxylate to a primary amine

  2019-07-24

  

  CAA is a carcinogenic metabolite of vinyl chloride, forming several different DNA adducts including the cyclic urat1 inhibitor adducts 3,N4-ethenocytosine (εC), 1,N6-ethenoadenine (εA), N2,3-ethenoguanine (εG), and 1,N2-ethenoguanine (1,N2-εG), with the A and C cyclic adducts the most predominant, a

  Results Discussion The importance of mitochondria for the initiation and progression of tumorigenesis is now emerging. It is evident that, despite the well-known Warburg effect, tumors have active mitochondrial bioenergetic metabolism (Marin-Valencia et al., 2012, Hensley et al., 2016). Disrup

  Electron transfer pathway Intramolecular (or inter-domain) electron transfer (IET) in CDH has been studied in much depth [], and similar IET occurs in CcPDH, from the PQQ cofactor in the AA12 domain to the heme b in the AA8 domain. When two kinds of electron acceptors are used for measuring enzym

  Accurate equilibrium predictions of CO2 containing mixtures, however, are challenging with traditional equations of state. The reason for this may be that CO2 has a large quadrupole moment. The large quadrupole moment of CO2, as well as size asymmetry, are for instance believed to be the reasons for

  2019-07-23

  

  Initially, the E1 uses ATP to activate the C-terminal glycine residue of ubiquitin prior to ligation. In the first step of E1 activation, the E1 catalyzes the adenylation of ubiquitin and pyrophosphate (PPi) release. In the second step, the E1 releases adenosine monophosphate (AMP) and a thioester b

  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

  Enlarging the ligand-binding pocket by reduction of the size of the residue F435 switched DES to an agonist indicating that F435 is involved in mediating the antagonistic effect of DES (Fig. 7E) [13]. The conformation of the smaller side chain of L435 was either not altered by DES or was too small t
