The goal of the study was to understand the regulation of the enzymatic steps associated with biomethane biosynthesis by H-2, using metagenomic, pan-genomic, and transcriptomic approaches. Methanogenesis in the autotrophic methanogen M. fervens could be easily "switched off" and "switched on" by H-2/CO2 within about an hour. In contrast, the heterotrophic methanogen M. thermophilum was practically insensitive to the addition of the H-2/CO2 trigger although this methanogen also converted H-2/CO2 to CH4. From practical points of view, the regulatory function of H-2/CO2 suggests that in the power-to-gas (P2G) renewable excess electricity conversion and storage systems, the composition of the biomethane-generating methanogenic community is essential for sustainable operation. In addition to managing the specific hydrogenotrophic methanogenesis biochemistry, H-2/CO2 affected several, apparently unrelated, metabolic pathways. The redox-regulated overall biochemistry and symbiotic relationships in the methanogenic communities should be explored in order to make the P2G technology more efficient.}, keywords = {metabolism; IDENTIFICATION; HYDROGEN; REDUCTION; METHANE; ACETATE; STRAINS; ANAEROBIC-DIGESTION; methanogenesis; Dehydrogenases; Hydrogenotrophic methanogens; Power to gas; THERMOPHILICUM}, year = {2023}, eissn = {1432-0614}, pages = {6315-6324}, orcid-numbers = {Szuhaj, Márk/0000-0001-7160-3173; Kakuk, Balázs/0000-0002-4314-5707; Wirth, Roland/0000-0002-2383-2323; Rákhely, Gábor/0000-0003-2557-3641; Kovács, Kornél Lajos/0000-0002-3926-0497; Bagi, Zoltán/0000-0001-7795-2024} } @article{MTMT:34108330, title = {Bioelectrochemical Systems (BES) for Biomethane Production-Review}, url = {https://m2.mtmt.hu/api/publication/34108330}, author = {Horváth-Gönczi, Noémi Nikolett and Bagi, Zoltán and Szuhaj, Márk and Rákhely, Gábor and Kovács, Kornél Lajos}, doi = {10.3390/fermentation9070610}, journal-iso = {FERMENTATION-BASEL}, journal = {FERMENTATION}, volume = {9}, unique-id = {34108330}, abstract = {Bioelectrochemical systems (BESs) have great potential in renewable energy production technologies.

Therefore, there is an urgent need to develop new antifungal treatment strategies. The features of a disulfide bond-stabilized antifungal protein, NFAP2 secreted by the mold Neosartorya (Aspergillus) fischeri render it to be a promising template for future protein-based antifungal drug design, which requires knowledge about the native disulfide linkage pattern as it is one of the prerequisites for biological activity. However, in the lack of tryptic and chymotryptic proteolytic sites in the ACNCPNNCK sequence, the determination of the disulfide linkage pattern of NFAP2 is not easy with traditional mass spectrometry-based methods. According to in silico predictions working with a preliminary nuclear magnetic resonance (NMR) solution structure, two disulfide isomers of NFAP2 (abbacc and abbcac) were possible. Both were chemically synthesized; and comparative reversed-phase high-performance liquid chromatography, electronic circular dichroism and NMR spectroscopy analyses, and antifungal susceptibility and efficacy tests indicated that the abbcac is the native pattern. This knowledge allowed rational modification of NAFP2 to improve the antifungal efficacy and spectrum through the modulation of the evolutionarily conserved gamma-core region, which is responsible for the activity of several antimicrobial peptides. Disruption of the steric structure of NFAP2 upon gamma-core modification led to the conclusions that this motif may affect the formation of the biologically active three-dimensional structure, and that the gamma-core modulation is not an efficient tool to improve the antifungal efficacy or to change the antifungal spectrum of NFAP2.}, keywords = {DYNAMICS; PREDICTION; DRUG DESIGN; BONDS; protein structure; ANTIFUNGAL PROTEIN; disulfide linkage pattern}, year = {2023}, eissn = {1469-896X}, orcid-numbers = {Váradi, Györgyi/0000-0001-7907-8908; Kele, Zoltán/0000-0002-4401-0302; Papp, Csaba Gergő/0000-0003-4450-0667; Rákhely, Gábor/0000-0003-2557-3641; Tóth, Gábor/0000-0002-3604-4385; Batta, Gyula/0000-0002-0442-1828; Galgóczi, László Norbert/0000-0002-6976-8910} } @{MTMT:34012624, title = {Intracellular ProteinTargets of Neosartorya (Aspergillus) fischeri Antifungal Proteins}, url = {https://m2.mtmt.hu/api/publication/34012624}, author = {Dán, Kinga and Zoltán, Kele and Tóth, Liliána and Fanni, Marcsisák and Gábor, K.

More than one CYB561 can be found in a wide range of animal and plant phyla and they are localized in membranes different from the membranes participating in bioenergization. Two homologous proteins, both in humans and rodents, are thought to participate—via yet unidentified way—in cancer pathology.

In the present work, the anticancer activity of symmetrical selenoesters was investigated by studying the reversal of efflux pump-related and apoptosis resistance in sensitive and resistant human colon adenocarcinoma cells expressing the ABCB1 protein. The combined effect of the compounds with doxorubicin was demonstrated with a checkerboard assay. The ABCB1 inhibitory and the apoptosis-inducing effects of the derivatives were measured with flow cytometry. Whole transcriptome sequencing was carried out on Illumina platform upon the treatment of resistant cells with the most potent derivatives. One ketone and three methyl ester selenoesters showed synergistic or weak synergistic interaction with doxorubicin, respectively. Ketone selenoesters were the most potent ABCB1 inhibitors and apoptosis inducers. Nitrile selenoesters could induce moderate early and late apoptotic processes that could be explained by their ABCB1 modulating properties. The transcriptome analysis revealed that symmetrical selenoesters may influence the redox state of the cells and interfere with metastasis formation. It can be assumed that these symmetrical selenocompounds possess toxic, DNA-damaging effects due to the presence of two selenium atoms in the molecule, which may be augmented by the presence of symmetrical groups.}, year = {2023}, eissn = {1999-4923}, orcid-numbers = {Rácz, Bálint/0000-0003-0088-3408; Kincses, Annamária/0000-0002-1591-1419; Laczi, Krisztián/0000-0002-9399-7406; Rákhely, Gábor/0000-0003-2557-3641; Domínguez-Álvarez, Enrique/0000-0003-2655-1575; Spengler, Gabriella/0000-0001-8085-0950} }
