  • Glucosamine-6-phosphate synthase with an oligoHis insert

    Publication

    - Acta Biochimica Polonica - Year 2010

    Glucosamine-6-phosphate (GlcN-6-P) synthase known also as L-Glutamine: D-fructose-6-phosphate aminotransferase (EC 2.6.1.16), catalyzes the first committed step in the amino sugar biosynthetic pathway in prokaryotic and eukaryotic organisms. The final product of this pathway is an activated precursor of numerous macromolecules containing amino sugars, including chitin and mannproteins in fungi, peptydoglican and lipopolysaccharides...

  • Glucosamine-6-phosphate synthase - the multi-facets enzyme

    Amidotransferaza L-glutamina: D-frukozo-6-fosforan, nazywana zwyczajowo syntazą glukozamino-6-fosforanu, jako jedyny enzym należący do grupy amidotransferaz, nie wykazuje aktywności amoniakozależnej. Enzym ten, katalizujący pierwszy wyjątkowy etap w szlaku metabolicznym prowadzącym do ostatecznego wytworzenia 5´difosfourydyno-N-acetylo-D-glukozaminy (UDG-GlcNAc) stanowi ważny punkt kontroli metabolicznej biosyntezy makromolekuł...

  • Desensitization of glucosamine-6-phosphate synthase to inhibition by UDP-GlcNAc

    Glucosamine-6-phosphate (GlcN-6-P) synthase, known also as L-Glutamine: D-fructose-6-phosphate amidotransferase, catalyzes the first committed step in the pathway leading to the ultimate formation of UDP-GlcNAc. The final product of this pathway is an activated precursor of numerous macromolecules containing amino sugars, including chitin and mannproteins in fungi, peptidoglycan and lipopolysaccharides in bacteria, and glycoproteins...

  • Construction of glucosamine-6-phosphate synthase with an internal hexahistydyl fragment

    Publication
    • K. Kwiatkowska
    • J. Czarnecka

    - Year 2010

    L-Glutamine: D-fructose-6-phosphate aminotransferase (EC 2.6.1.16), known also as glucosamine-6-phosphate (GlcN-6-P) syntase, catalyzes the first committed step in the amino sugar biosynthetic pathway in prokaryotic and eukaryotic organisms. The enzyme carries out a complex reaction involving ammonia transfer and sugar phosphate isomerization. GlcN-6-P syntase is an important point of metabolic control of amino sugar biosynthesis...

  • Allosteric control of Candida albicans glucosamine-6-phosphate synthase.

    Publication

    Przedstawiono wyniki badań spektrofluorymetrycznych syntazy GlcN-6-P z Candida albicans oraz enzymu zmutowanego, w którym reszty Trp388 i 690 zostały zamienione na drodze ukierunkowanej mutagenezy na reszty Phe. Metodą spektrofluorymetryczną badano wpływ ligandów: Fru-6-P (substrat), Gln (substrat), UDP-GlcNAc (inhibitor), Glc-6-P (aktywator), DON (analog glutaminy) w odpowiednio dobranych stężeniach. Obecność większości efektorów...
