  • Biochemistry and Molecular Genetics of the Biosynthesis of the Earthy Odorant Methylisoborneol in <i>Streptomyces coelicolor</i>
    作者:Chieh-Mei Wang、David E. Cane

    Methylisoborneol (2) is a volatile organic compound produced by a wide variety of Actinomycetes soil orgainisms, myxobacteria, and cyanobacteria. It has an unusually low odor threshold and, together with geosmin, is responsible for the characteristics smell of moist soil as well as unpleasant taste and odor episodes assoiciated with public water supplies and contamination of various foodstuffs, including fish, wine and beer. Despite considerable interest in detection and remediation of methylisoborneal, the biosynthesis of this methylated monoterpene has been obscure. In Streptomyces coelicor, the sco7700 and sco7701 genes are shown to correspond to a two-gene operon responsible for methylisoborneol biosynthesis. Both genes have been amplified by PCR and the resulting DNA has been cloned and expressed in Escherichia coli. Incubation of recombinant SCO7701 protein, annotated as a possible C-methyltransferase, with geranyl diphosphate (1) and S-adenosylmethionine gave the previously unknown compound. (E)-2-methylgeranyl diphosphate (3). Incubation of 3 in the presence of Mg2+ with recombinant SCO7700, previously annotated only as a possible metal-binding protein or terpenoid synthase, resulted in the formation of 2-methylisoborneal (2). The steady-state kinetic parameters for both biochemical reactions have been determined. Incubation of geranyl diphosphate and S-adenosylmethionine with a mixture of both SCO7700 and SCO7701 resulted in formation of methylisoborneal (2). Cyclization of 2-methylgeranyl diphosphate (3) to methylisoborneal (2) likely involves the intermediacy of 2-methylinalyl diphosphate.
  • Incubation of 2-methylisoborneol synthase with the intermediate analog 2-methylneryl diphosphate

    Incubation of synthetic 2-methylneryl diphosphate (2-MeNPP, 10) with 2-methylisoborneol synthase (MIBS) gave a mixture of products that differed significantly from that derived from the natural substrate (E)-2-methylgeranyl diphosphate (3, 2-MeGPP). The proportion of (-)-2-methylisoborneol (1) decreased from 89 to 17% while that of 2-methylenebornane (4) increased from 10 to 26%, with the relative yields of the isomeric homo-monoterpenes 2-methyl-2-bornene (5) and 1-methylcamphene (6) remaining essentially unchanged (<1% each), as determined by chiral GC–MS analysis. The majority of the product mixture resulting from the MIBS-catalyzed cyclization of 2-MeNPP (10) consisted of the anomalous monocyclic homo-monoterpenes (±)-2-methylllimonene (15, 39%) and 2-methyl-α-terpineol (13, 10%), as well as the acylic derivatives 2-methylnerol (11, 7%) and 2-methyllinalool (14, <1%). The steady-state kinetic parameters of the MIBS-catalyzed reaction, determined using [1-3H]-2-methylneryl diphosphate (2-MeNPP), were kcat 0.0046±0.0003 s−1, Km 18±6 μm and kcat/Km 2.55 × 102 M−1 s−1. In comparison, the natural substrate 2-MeGPP had a kcat 0.105±0.007 s−1, Km 95±49 μm and kcat/Km 1.11 × 103 M−1 s−1. Taken together with earlier X-ray crystallographic studies of MIBS, as well as previous investigations of the mechanistically related plant monoterpene cyclase, bornyl diphosphate synthase, these results provide important insights into the binding and cyclization of both native substrates and intermediates and their analogs.
