Studies of the FBT family transporters in Leishmania infantum by gene deletion and protein localization.

The protozoan parasite Leishmania has a large family of major facilitator membrane proteins part of the Folate Biopterin Transporter (FBT) family. The chromosome 10 of Leishmania has a cluster of 7 FBT genes including the S-Adenosyl methionine (AdoMet) transporter and the functionally characterized folate transporters FT1 and FT5. Six of the 7 FBT proteins coded by this locus are located at the plasma membrane as determined by gene fusions with the green fluorescent protein.

New experimental methodology for determining the second crossover energy in insulators under stationary e-irradiation in a SEM.

A new experimental methodology is proposed which uses the electrostatic influence method (EIM) in scanning electron microscope (SEM) in order to estimate the second crossover energy E for uncharged insulators. This experimental methodology based on simultaneous time measurement of the displacement and leakage currents, is approached to the short pulse irradiation technique but under stationary e-irradiation and allows determining the intrinsic secondary electron emission yield, σ (σ is the value of the total secondary electron yield just at the beginning of the irradiation before significant charge accumulation or before the formation of a surface potential). The obtained value of E for soda-lime glass is confirmed by two additional experiments based on secondary electron imaging.

Impact of missense mutations on the structure-function relationship of human succinyl-CoA synthetase using in silico analysis.

The encephalomyopathic mtDNA depletion syndrome with methylmalonic aciduria is associated with succinyl-CoA synthetase (SCS) deficiency caused by pathogenic variants in genes encoding its two subunits. SCS is a mitochondrial enzyme involved in several metabolic pathways and acts as a heterodimer composed of α and β subunits encoded by SUCLG1 and SUCLA2 genes, respectively. The purpose of this study was to analyze the effects of the most pathogenic non-synonymous single nucleotide polymorphisms (nsSNPs) by applying, using different prediction tools, a filtering strategy, on the 343 and 365 nsSNPs found in SUCLG1 and SUCLA2 genes, respectively, retrieved from the databases, then to evaluate their structural and functional effects using homology modeling and molecular docking.
