Conformational Dynamics of Mitochondrial Inorganic Pyrophosphatase hPPA2 and Its Changes Caused by Pathogenic Mutations.

Chemistry Department, Lomonosov Moscow State University, 119991 Moscow, Russia.
Inorganic pyrophosphatases, or PPases, are ubiquitous enzymes whose activity is necessary for a large number of biosynthetic reactions. The catalytic function of PPases is dependent on certain conformational changes that have been previously characterized based on the comparison of the crystal structures of various complexes. The current work describes the conformational dynamics of a structural model of human mitochondrial pyrophosphatase hPPA2 using molecular dynamics simulation, all-atom principal component analysis, and coarse-grained normal mode analysis.

Road activities are recognized sources of pollution that affect the hydrochemistry of nearby water bodies. This study evaluated the Water Quality Monitoring Program in the Soberbo and Iconha rivers in the Guapi-Macacu watershed, which is affected by the BR-116 highway. The Rio-Teresópolis Concessionaire from 2009 to 2016 carried out quarterly sampling.

Background: The transcription factor AP1 plays a crucial role in the proliferation, apoptosis, and terminal differentiation of epidermal keratinocytes.
Objective: This study aimed to clarify whether the subunit of AP1, FOSL1 protein, can be used to assess the exacerbation of psoriasis by evaluating its changes in protein and mRNA levels in cultured epidermal keratinocytes and skin specimens of the patients prescribed with bathwater PUVA (Psoralen and UVA) therapy. This study aimed to investigate FOSL1, a subunit of the transcription factor AP-1, as a potential biomarker for psoriasis by examining its protein and mRNA expression in skin specimens from patients undergoing bathwater PUVA (Psoralen and UVA) therapy and cultured epidermal keratinocytes.
Synthesis of zwitterionic asymmetric and symmetric carboxy-imidazolium derivatives and their use in molecular interactions with bovine serum albumin.

A. M. Butlerov Institute of Chemistry, Kazan Federal University, Kremlevskaya str. 18, Kazan 420018, Russia.
For the first time asymmetric and symmetric carboxytriazoleimidazolium derivatives with different structures were synthesized. The critical micellization concentration (CMC) value was estimated using a pyrene fluorescent probe and the solubility of Orange OT. The complexation ability of carboxytriazoleimidazolium derivatives toward bovine serum albumin (BSA) has been investigated by various physico-chemical methods: fluorescence spectroscopy, electrophoretic light scattering and circular dichroism.
