Indications for a Central Role of Hexokinase Activity in Natural Variation of Heat Acclimation in Arabidopsis Thaliana
Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 14 June 2020 doi:10.20944/preprints202006.0169.v1 Article Indications for a central role of hexokinase activity in natural variation of heat acclimation in Arabidopsis thaliana Vasil Atanasov §, Lisa Fürtauer § and Thomas Nägele * LMU Munich, Plant Evolutionary Cell Biology, Großhaderner Str. 2-4, 82152 Planegg, Germany § Authors contributed equally * Correspondence: [email protected] Abstract: Diurnal and seasonal changes of abiotic environmental factors shape plant performance and distribution. Changes of growth temperature and light intensity may vary significantly on a diurnal, but also on a weekly or seasonal scale. Hence, acclimation to a changing temperature and light regime is essential for plant survival and propagation. In the present study, we analyzed photosynthetic CO2 assimilation and metabolic regulation of the central carbohydrate metabolism in two natural accessions of Arabidopsis thaliana originating from Russia and south Italy during exposure to heat and a combination of heat and high light. Our findings indicate that it is hardly possible to predict photosynthetic capacities to fix CO2 under combined stress from single stress experiments. Further, capacities of hexose phosphorylation were found to be significantly lower in the Italian than in the Russian accession which could explain an inverted sucrose-to-hexose ratio. Together with the finding of significantly stronger accumulation of anthocyanins under heat/high light these observations indicate a central role of hexokinase activity in stabilization of photosynthetic capacities within a changing environment. Keywords: photosynthesis; carbohydrate metabolism; hexokinase; heat acclimation; environmental changes; natural variation; high light; combined stress. 1. Introduction Changes of growth temperature and light intensity broadly affect plant molecular, physiological and developmental processes. -
Non-Homologous Isofunctional Enzymes: a Systematic Analysis Of
Omelchenko et al. Biology Direct 2010, 5:31 http://www.biology-direct.com/content/5/1/31 RESEARCH Open Access Non-homologousResearch isofunctional enzymes: A systematic analysis of alternative solutions in enzyme evolution Marina V Omelchenko, Michael Y Galperin*, Yuri I Wolf and Eugene V Koonin Abstract Background: Evolutionarily unrelated proteins that catalyze the same biochemical reactions are often referred to as analogous - as opposed to homologous - enzymes. The existence of numerous alternative, non-homologous enzyme isoforms presents an interesting evolutionary problem; it also complicates genome-based reconstruction of the metabolic pathways in a variety of organisms. In 1998, a systematic search for analogous enzymes resulted in the identification of 105 Enzyme Commission (EC) numbers that included two or more proteins without detectable sequence similarity to each other, including 34 EC nodes where proteins were known (or predicted) to have distinct structural folds, indicating independent evolutionary origins. In the past 12 years, many putative non-homologous isofunctional enzymes were identified in newly sequenced genomes. In addition, efforts in structural genomics resulted in a vastly improved structural coverage of proteomes, providing for definitive assessment of (non)homologous relationships between proteins. Results: We report the results of a comprehensive search for non-homologous isofunctional enzymes (NISE) that yielded 185 EC nodes with two or more experimentally characterized - or predicted - structurally unrelated proteins. Of these NISE sets, only 74 were from the original 1998 list. Structural assignments of the NISE show over-representation of proteins with the TIM barrel fold and the nucleotide-binding Rossmann fold. From the functional perspective, the set of NISE is enriched in hydrolases, particularly carbohydrate hydrolases, and in enzymes involved in defense against oxidative stress. -

Adaptive Laboratory Evolution Enhances Methanol Tolerance and Conversion in Engineered Corynebacterium Glutamicum
ARTICLE https://doi.org/10.1038/s42003-020-0954-9 OPEN Adaptive laboratory evolution enhances methanol tolerance and conversion in engineered Corynebacterium glutamicum Yu Wang 1, Liwen Fan1,2, Philibert Tuyishime1, Jiao Liu1, Kun Zhang1,3, Ning Gao1,3, Zhihui Zhang1,3, ✉ ✉ 1234567890():,; Xiaomeng Ni1, Jinhui Feng1, Qianqian Yuan1, Hongwu Ma1, Ping Zheng1,2,3 , Jibin Sun1,3 & Yanhe Ma1 Synthetic methylotrophy has recently been intensively studied to achieve methanol-based biomanufacturing of fuels and chemicals. However, attempts to engineer platform micro- organisms to utilize methanol mainly focus on enzyme and pathway engineering. Herein, we enhanced methanol bioconversion of synthetic methylotrophs by improving cellular tolerance to methanol. A previously engineered methanol-dependent Corynebacterium glutamicum is subjected to adaptive laboratory evolution with elevated methanol content. Unexpectedly, the evolved strain not only tolerates higher concentrations of methanol but also shows improved growth and methanol utilization. Transcriptome analysis suggests increased methanol con- centrations rebalance methylotrophic metabolism by down-regulating glycolysis and up- regulating amino acid biosynthesis, oxidative phosphorylation, ribosome biosynthesis, and parts of TCA cycle. Mutations in the O-acetyl-L-homoserine sulfhydrylase Cgl0653 catalyzing formation of L-methionine analog from methanol and methanol-induced membrane-bound transporter Cgl0833 are proven crucial for methanol tolerance.

In the whole cell biocatalysis, recombinant CMP kinase catalyzed the conversion of CMP to CDP, and endogenous acetate kinase of the E. coli was utilized for the ATP regeneration as well as for the conversion of CDP to CTP. A conversion yield of ca. 88 % CTP was obtained when starting with 20 mM CMP, 1 mM ATP, and 80 mM acetyl phosphate based on the initial CMP concentration. Endogenous pyruvate kinase and poly- phosphate kinase were inefficient in the process. The CTP production system was applied to the production of CMP-NeuAc by additionally introducing the CMP-NeuAc synthetase gene into the recombinant E. coli.
