Inhibitory Kunitzova typu u Eudiplozoon nipponicum / Kunitz-type inhibitors in Eudiplozoon nipponicum

Černíková, Markéta January 2021 (has links)
Proteins containing Kunitz domain are mostly inhibitors of serine proteases. Their general characteristic is the presence of three disulfide bonds and small sizes around 6-10 kDa, although sometimes they consist of several Kunitz domains or they are part of more complex proteins. Their function is usually related to the regulation of physiological and proteolytic processes, but also to an interaction with pathogens or other defense mechanisms, such as being part of the sea anemone mucus or the venom of snakes and other invertebrates. We focused on Kunitz proteins in Eudiplozoon nipponicum, a helminth of the class Monogenea parasiting on gills of common carp (Cyprinus carpio). In the transcriptome of this parasite, several sequences with Kunitz domain have been identified based on similarities with the one already described Kunitz protein, EnKT1, suggesting that this parasite, like other bloodfeeding parasites, uses a whole set of these serine protease inhibitors with other specific functions. Several sequences with the Kunitz domain found in the transcriptome were verified by PCR and optionally supplemented by RACE-PCR. One protein, called EnKC1, was subsequently produced by recombinant expression in E. coli cells of SHuffleTM and Rosetta Gami B strains. Recombinant protein with the Kunitz domain...

Analýza a mapování vazebných míst regulátorů genové exprese u streptomycet. / Analysis and mapping of binding sites of gene expression regulators in the genus of Streptomyces.

Šmídová, Klára January 2020 (has links)
Streptomyces are medically important soil-living bacteria that undergo morphological changes from spores to aerial hyphae and are important producers of bioactive compounds including antibiotics. Their gene expression is tightly regulated at the early level of transcription and translation. In the transcriptional control, sigma factors play a central role; the model organism Streptomyces coelicolor possesses astonishing 65 sigma factors. The expression of sigma factors themselves is controlled on the post-transcriptional level through the action of sRNAs that modify their mRNA level. However, only several sigma factors in Streptomyces have known regulons and also their sRNAs-mediated regulation has not been studied so far. According to previously measured gene expression data, we selected several highly expressed sigma factors. Using mutant strains with HA-tagged sigma factors, regulons of two important sigma factors, SigQ and HrdB, were analyzed by ChIP-seq procedure. Other sigma factors were further studied to see if they possess asRNAs, using 5' and 3' RACE method and northern blotting. Our data confirm the essentiality of HrdB sigma factor during the vegetative phase of growth. The other sigma factor, SigQ, has been revealed to be an important regulator of nitrogen metabolism and osmotic...

Identifiering och utvärdering av värdedrivare under komplexa tjänsteleveranser : En fallstudie av kollektivtrafikleveranserna vid Trafikförvaltningen, Region Stockholm / Identification and assessment of value drivers during complex service deliveries : A case study through the public transport deliveries at Trafikförvaltningen, Region Stockholm

Gustavsson, Markus January 2023 (has links)
Offentligt upphandlade tjänster omsätter omkring 800 miljarder SEK per år och står för omkring 20% av Sveriges BNP. Offentlig upphandling av tjänster står för omkring 43% av alla offentligt upphandlade affärer vilket gör upphandling av tjänster en vanligare typ av affär än upphandling av produkter. Trots detta har det akademiska intresset för vad som driver värde inom offentligt upphandlade affärer varit lågt, och intresset för offentligt upphandlade tjänster ännu lägre. För att förstå vad som driver värde under kontraktsperioden i en offentligt upphandlad tjänsteaffär har Trafikförvaltningen i Stockholm valts som fallföretag. Trafikförvaltningen är den organisation som upphandlar och förvaltar kollektivtrafiken i Stockholm och kollektivtrafiken i Stockholm har cirka två miljoner påstigande varje dag. Studiens syfte är därför att undersöka vilka faktorer som driver kundvärde under komplexa tjänsteleveranser och att definiera vad är värdedrivande på respektive faktor. För att åstadkomma detta genomfördes en litteraturstudie för att ta reda på vilka faktorer som vanligtvis är värdedrivande under affärer mellan företag, affärer mellan företag och statliga organisationer och under tjänsteleveranser. Detta resulterade i en analysmodell som därefter prövades explorativt genom 14 djupintervjuer med affärsförvaltare och affärsområdesansvariga på Trafikförvaltningen och en representant från Skånetrafiken respektive Västtrafik. Utifrån denna fallstudie kan det konstateras att följande faktorer definitivt är värdedrivare under B2G-tjänsteleveranser: Faktorn tjänstekvalitet, vilket innebär en hög kvalitet och prestanda, en hög kravuppfyllelse över tid och att tjänsten levereras så att kunden får tid att ägna sig åt sin kärnverksamhet. Faktorn tjänstehantering, vilket innebär ett ordentligt och förebyggande underhåll, en välfungerande fakturahantering och en välfungerande rapport- och dokumentationshantering. Faktorn leveransnoggrannhet, vilket innebär att leverera med exakthet och att leverantören gör allt i sin makt för att leverera tjänsten så exakt som möjligt. Faktorn möjligheter att växa, vilket innebär att leverantören levererar sin tjänst på ett sådant sätt att kunden kan växa i marknadsandel och antal slutkunder. Faktorn utvecklingsmöjligheter, vilket innebär kontinuerliga förbättringar av verksamheten och att leverantören aktivt arbetar för att utveckla processer och rutiner. Faktorn organisatoriska förmågor, vilket innebär att leverantörens samarbete med andra aktörer ska fungera på ett professionellt och ansvarstagande vis, att leverantören har en stor kunskap- och avtalsförståelse, ett helhetsperspektiv - inte bara ett ekonomiskt perspektiv, tar ett arbetsgivaransvar samt har avtalsstöd när förhandlingar uppstår. Faktorn intressentrelationer, vilket innebär en hög kundnöjdhet (slutkunderna) och att leverantören aktivt jobbar för att öka denna, att leverantören levererar tjänsten utan att skada kundens varumärke och anseende samt att leverantören skapar socialt värde genom att värde skapas för allmänheten. Faktorn leverantörsrelation, vilket innebär att leverantören ska ha en god personlig interaktion, en hög lyhördhet och god samtalston, skapar tillit och förtroende, är lösningsorienterade i förhandlingar samt inte har ett opportunistiskt beteende. Sist men inte minst, faktorn interaktion, vilket innebär ett professionellt och affärsmässigt bemötande, en hög tillgänglighet, transparens och respektfullhet samt förstår den offentliga förvaltningens roll i affären.

Transkripční regulace proteinu PIN4, membránového přenašeče rostlinného hormonu auxinu / Transcriptional regulation of PIN4 protein, membrane transporter of plant hormone auxin.

Hurný, Andrej January 2012 (has links)
PIN-FORMED (PIN) proteins are plant-specific secondary transporters acting in the efflux of plant signaling molecule auxin from cells. Their asymmetrical localization within cells determines the directionality of auxin flow and thereby influences plant development. The activity of PIN proteins is regulated at multiple levels; however the primary step in the regulation of PIN proteins takes place at the level of gene transcription. Therefore the main focus of this diploma thesis is the characterization of the transcriptional regulation of PIN proteins, namely PIN4 protein. The observation of plants carrying transcriptional fusion consisting of various lengths of PIN4 promoter and green fluorescent protein (GFP) showed which part of PIN4 promoter is essential for binding transcription factors and for the start of transcription. This part of PIN4 promoter was used as bait for transcription factors in yeast one hybrid screens. Altogether, 24 transcription factors were identified in which the most numerous were transcription factors from GATA and APETALA2 (AP2)/ETHYLENE RESPONSE FACTOR (ERF) families. To verify the interactions between identified transcription factors and PIN4 promoter, the protoplast transient expression assay was used. Protoplasts isolated from Arabidopsis thaliana leaves and tobacco BY-2 cell...
