    Acord transformatiu CRUE-CSICHere we consider several macroeconomic indicators taken from the Federal State Statistics Service (2019). First, there is the inflation rate calculated for each month as the sum of the inflation coefficients for the previous 12 months. Second, the unemployment rate is defined as the proportion of the unemployed in the economically active population. Further, the real wage index is calculated by dividing the nominal wage index by the consumer price index of the same period. Finally, budget expenditures are the funds of the federal and consolidated regional budgets directed to financial support of the tasks and functions of the federal and regional governments.Altres ajuts: This research has been supported by the Russian Science Foundation, project No. 19-18-00262 "Modelling a balanced technological and socio-economic development of the Russian regions".The addresses of national leaders can affect their public support and spur changes in the country's economy. To date, very few studies exist establishing these relationships, and no research has been done on the addresses from Vladimir Putin. In this paper we fill this knowledge gap by analysing the nationwide phone-ins of Putin, a special annual format where he addresses the public, and using structural topic modelling studying their topics over time. Furthermore, we relate these topics to public approval of the president and the government as well as to some Russian macroeconomic indicators such as inflation and budget expenditures. Based on our data containing 1938 responses and almost 250 thousand words, we identify 16 main topics covering areas from healthcare and education through economics to elections and legislation. We find that the topic of foreign affairs has gained in popularity over time the most (from around 4.5% at the beginning to more than 10% starting from 2014). Another topic, consistently gaining weight in the president's statements, is related to solving particular problems of the general public (from 8% to 12.5%) and is significantly correlated with subsequent decrease in the country's unemployment (Pearson's correlation coefficient -0.502). We also find that when the government's support is decreasing, Putin tends to discuss more socially significant topics (e.g., inflation, healthcare, Pearson's coef. around -0.5), while when the support is rising, he speaks more about foreign affairs (Pearson's coef. 0.773). Our study provides first evidence that Vladimir Putin may adapt the content of his phone-in meetings to gather public support and influence the country's economy

    Involvement of the C terminus in intramolecular nitrogen channeling in glucosamine 6-phosphate synthase: evidence from a 1.6 å crystal structure of the isomerase domain

    AbstractBackground: Glucosamine 6-phosphate synthase (GlmS) catalyses the first step in hexosamine metabolism, converting fructose-6P (6 phosphate) into glucosamine-6P using glutamine as a nitrogen source. GlmS is a bienzyme complex consisting of two domains that catalyse glutamine hydrolysis and sugar-phosphate isomerisation, respectively. Knowledge of the three-dimensional structure of GlmS is essential for understanding the general principles of catalysis by ketol isomerases and the mechanism of nitrogen transfer in glutamine amidotransferases.Results: The crystal structure of the isomerase domain of the Escherichia coli GlmS with the reaction product, glucosamine-6P, has been determined at 1.57 å resolution. It is comprised of two topologically identical subdomains, each of which is dominated by a nucleotide-binding motif of a flavodoxin type. The catalytic site is assembled by dimerisation of the protein.Conclusions: The isomerase active site of GlmS seems to be the result of evolution through gene duplication and subsequent dimerisation. Isomerisation of fructose-6P is likely to involve the formation of a Schiff base with Lys603 of the enzyme, the ring-opening step catalysed by His504, and the proton transfer from C1 to C2 of the substrate effected by Glu488. The highly conserved C-terminal fragment of the chain may play a key role in substrate binding, catalysis and communication with the glutaminase domain. The corresponding sequence pattern DXPXXLAK[SC]VT (in single-letter amino-acid code, where X is any amino acid and letters in brackets indicate that either serine or cysteine may take this position) may be considered as a fingerprint of GlmS

    The two m-dimensional surfaces in n-dimensional projective space between which points a point conformity is establishedis studied. The network of lines is given on surfaces. Some geometrical images connected with the network are considered. Consideration has everywhere local character. All functions considered in the given work are assumed analytical
