Additionally, the browser supports direct Javascript coding for personalised tracks, providing a whole new level of customisation both functionally and visually. Tracks can be added via direct file upload or processed in real-time via links to files stored remotely on an FTP repository. Furthermore, additional tracks can be added by users via simple drag and drop to an existing visualisation instance.

Plant organellar DNA polymerases (DNAPs) are not phylogenetically related to yeast and metazoan DNAPs and they harbor three insertions not present in any other DNAPs. Plant organellar DNAPs from Arabidopsis thaliana (AtPolIA and AtPolIB) are translesion synthesis (TLS) DNAPs able to bypass abasic sites, a lesion that poses a strong block to replicative polymerases. Besides abasic sites, reactive oxidative species and ionizing radiation react with thymine resulting in thymine glycol (Tg), a DNA adduct that is also a strong block to replication. Here, we report that AtPolIA and AtPolIB bypass Tg by inserting an adenine opposite the lesion and efficiently extend from a Tg-A base pair. The TLS ability of AtPolIB is mapped to two conserved lysine residues K593 and K866. Residue K593 is situated in insertion 1 and K866 is in insertion 3. With basis on the location of both insertions on a structural model of AtPolIIB, we hypothesize that the two positively charged residues interact to form a clamp around the primer-template. In contrast with nuclear and bacterial replication, where lesion bypass involves an interplay between TLS and replicative DNA polymerases, we postulate that plant organellar DNAPs evolved to exert replicative and TLS activities. © 2020 The Author(s).

Here, we present Bio2Rxn as a web-based tool to provide putative enzymatic reaction predictions for uncharacterized protein sequences. Bio2Rxn adopts a consensus strategy by incorporating six types of enzyme prediction tools. It allows for the efficient integration of these computational resources to maximize the accuracy and comprehensiveness of enzymatic reaction predictions, which facilitates the characterization of the functional roles of target proteins in metabolism. Bio2Rxn further links the enzyme function prediction with more than 300,000 enzymatic reactions, which were manually curated by more than 100 people over the past 9 years from more than 580,000 publications. AVAILABILITY Bio2Rxn is available at http//design.rxnfinder.org/bio2rxn/. SUPPLEMENTARY INFORMATION Supplementary data are available at Bioinformatics online. © The Author(s) (2020).

This study has demonstrated that iron in varying concentrations (up to 400 µM) causes an increase in α-synuclein content in SH-SY5Y cells associated with mitochondrial depolarization, decreased cellular ATP content and loss of cell viability during incubation up to 96 h. Knocking-down α-synuclein expression prevents cytotoxic actions of iron, which can also be prevented by cyclosporine A (a blocker of mitochondrial permeability transition pore). These results indicate that iron cytotoxicity is mediated by α-synuclein acting on mitochondria. Likewise siRNA mediated knock-down of Parkin causes an accumulation of α-synuclein accompanied by mitochondrial dysfunction and cell death during 48 h incubation under basal conditions, but these changes are not further aggravated by co-incubation with iron (400 µM). We have also analyzed mitochondrial dysfunction and cell viability in SH-SY5Y cells under double knock-down (α-synuclein and Parkin concurrently) conditions during incubation for 48 h with or without iron. Our results tend to suggest that iron inactivates Parkin in SH-SY5Y cells and thereby inhibits the proteasomal degradation of α-synuclein, and the accumulated α-synuclein causes mitochondrial dysfunction and cell death. These results have implications in the pathogenesis of sporadic Parkinson's disease and also familial type with Parkin mutations.

Herein, a newly designed hybrid catalyst with manganese-doped FeNi-S encapsulated into graphene oxide (Mn@FeNi-S/GO) with unprecedented electrocatalytic activity was developed by simple one-step heat treatment followed by sonication. X-ray powder diffraction (XRD), Raman spectroscopy, Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microscopy (HR-TEM), X-ray photoelectron spectroscopy (XPS), and N2 sorption isotherm demonstrated the successful formation of Mn@FeNi-S/GO. Electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) further confirmed the kinetic-favourable adsorption of hydrogen peroxide (H2O2) onto the surface sites of Mn@FeNi-S/GO. Additionally, the synergetic effects between Mn@FeNi-S and GO are regarded as significant contributors to an efficient electron transfer path, and they promote the capture of H2O2 in hybrid catalysts.
