  Introduction DNA ligation is required during DNA replication and to complete almost all DNA repair events. In human cells, the DNA ligases encoded by three LIG genes are responsible for joining interruptions in the phosphodiester backbone [1]. These enzymes have distinct but overlapping functions

  Introduction Prolyl hydroxylation is a widely observed post translational modification in collagen, an abundant animal protein. The high content (~13% per chain of the triple helical structure) of 4-hydroxyproline (Hyp,O) in collagen, togather with the natural abundance of collagen has led to the e

  For this study we have used the intermediate affinity mutant antigen HEL2× for immunization. However, we have observed a similar defect in the plasmablast differentiation of EBI2-deficient SWHEL CPI-169 over a 10,000-fold affinity range by using WT HEL or the low-affinity mutant HEL3× (data not sho

  For these reasons, molecules of the ET family and in particular ET-1 are considered useful factors in the evaluation of malignancy and in consequence, in the prognosis for several forms of neoplasia, such as ovarian (Bagnato et al., 2005), prostate (Nelson et al, 1995, Nelson et al, 1996), colorecta

  2020-02-05

  

  From an industrial perspective, the low turnover numbers and limited substrate scope of α-KG halogenases still represents a significant challenge. However, in light of the fact that currently no chemical processes are available for the selective halogenation of aliphatic carbon centers in complex mo

• The Inhibitor of APoptosis IAP

  2020-02-05

  

  The Inhibitor of APoptosis (IAP) proteins were first identified as gene products of baculovirus that inhibited apoptosis of infected insect protease inhibitor cocktail (Clem et al., 1991, Crook et al., 1993). Subsequently, the mammalian IAP family was identified (Rothe et al., 1995, Uren et al., 19

  2020-02-05

  

  The fibrillogenesis process of collagen is understood to initiate in the extracellular space near the plasma membrane where secretory vesicles form regions of deep invagination. However, it is not clear how and when collagen-binding proteins interact with collagen molecules during fibrillogenesis or

  2020-02-05

  

  Overall, the DDR1 kinase domain has a typical kinase domain structure and adequate sequence and/or structure similarity with other kinase domains, as shown in Fig. 2, which allow homology modeling of the active and inactive conformations. In addition to conformational changes to the activation loop

  Discussion The membrane PVase activity components were discriminated in this work by pre-incubating with PMSF, mipafox, paraoxon or PMSF + mipafox to irreversibly inhibitPVase activity to discriminate the enzymatic components, (EPα, EPβ, EPγ and EPδ). The concentrations employed to discriminate t

  Introduction Mammalian proteases comprise both the peptidases or exopeptidases, which act at the N- or C-terminal positions of polypeptides, and proteinases or endopeptidases, which are capable of cleaving peptide bonds in the central regions of polypeptides. The endopeptidases are classified in

  Studies have focused on a hydrophobic cage at the CULT domain, conserved from bacteria to mammals, as it binds to substrates and IMiDs (Chamberlain et al., 2014, Lupas et al., 2015). In addition, CRBN ligand-mediated protein degradation was highly conserved, which was confirmed in vertebrates by foc

  In summary, these results are consistent with our hypothesis that chemical nitrosation of BMAA to N-BMAA results in the formation of an alkylating agent. Furthermore, we have shown that N-BMAA is more toxic than BMAA itself. Previously, methylazoxymethanol (MAM), which is also present in the cycad n

  The majority of serpins inhibit serine proteases, but serpins that inhibit caspases or papain-like cysteine proteases have also been identified [4], [5]. Inhibitory serpins are ‘suicide’ or ‘single use’ inhibitors that use a unique conformational change to inhibit proteases. This conformational tran
