    The initial steps in lincomycin biosynthesis

  • Original language description

    Protein LmbB1, involved in lincomycin biosynthesis in Streptomyces lincolnensis, was expressed in Escherichia coli and purified in its active form. It was found that it is a dimer consisting of identical subunits. By means of capillary electrophoresis and mass spectrometry, chemical structure of the reaction product of this protein was determined. LmbB1 was identified as dioxygenase catalyzing 2,3-extradiol splitting of L-3,4-dihydroxyphenylalanine (DOPA) aromatic ring. Protein LmbB2 was also expressedin E. coli and purified in its active form. It was identified as monooxidase catalyzing hydroxylation of tyrosine to DOPA

    Úvodní kroky v biosynthése lincomycinu

  • Czech description

    Protein LmbB1, který se účastní biosyntézy linkomycinu u Streptomyces lincolnensis byl exprimován v Escherichia coli a purifikován ve své aktivní formě. Bylo zjištěno, že se jedná o dimer složený z identických podjednotek. Pomocí kapilární elektroforézya hmotové spektrometrie byla určena struktura reakčního produktu tohoto proteinu. LmbB1 byl identifikován jako dioxygenasa, která katalyzuje 2,3-extradiolové štěpení aromatického kruhu L-3,4-dihydroxyfenylalaninu. Protein LmbB2 byl rovněž exprimován v E.coli a purifikován ve své aktivní formě. Bylo zjištěno, že se jedná o monooxidasu, která katalyzuje hydroxylaci tyrosinu na DOPA
