  • Scientists present a fully genetically encodable bioluminescent system science news XI.26

    Scientists from Russia, UK, Spain, Brazil, Japan, and Austria discovered the essential set of enzymes that allows glowing fungi to emit light. The bioluminescent system includes a brand- new luciferase and three enzymes that enable biosynthesis of fungal luciferin from a widespread metabolite – caffeic acid – as well as its recycling. The genes encoding this “caffeic acid cycle” make up a unique molecular toolkit that allows to turn any higher organism into a glowing one. The work was published in Proceedings of the National Academy of Sciences of the United States of America.

  • Kurt Wüthrich took part in the workshop of the Structural biology department science news X.10

    Professor Kurt Wüthrich, Nobel Laureate in Chemistry, 2002, visited Shemyakin–Ovchinnikov Institute of bioorganic chemistry RAS and took part in the workshop of the Structural biology department of the Institute (headed by Prof. Alexander Arseniev).

  • Ras-dva: make regeneration great again science news IX.17

    The researchers from Laboratory of molecular bases of embryogenesis recently hypothesised that the decrease of limb regeneration capacity in amniotes (reptiles, birds and mammals) could be caused by elimination in evolution of genes, encoding for important regulators of specific wound epithelium and blastema organization, which are used by excellent regenerating anamniotes (fish and amphibia). Using two anamniotic model organisms Danio rerio adult fishes and Xenopus laevis tadpoles the authors have shown the essential role of Ras-dva small GTPases in regulation of these processes, meanwhile their genes are eliminated in a stepwise manner during evolution till total absence in placental mammals. The obtained results support the hypothesis. The investigation is published in Scientific reports.
