Abstract
The present invention describes an efficient method for producing linalool. The present invention provides a method for producing linalool, the method including culturing a microorganism expressing linalool synthase in a culture medium to produce linalool. The present invention also describes a microorganism able to express linalool synthase and efficiently produce linalool.
Claims16
A method for producing linalool, the method comprising:
- (i) culturing a bacterium in a culture medium so that it is able to produce and cause accumulation of linalool, wherein the bacterium has an ability to synthesize dimethylallyl diphosphate via a methylerythritol phosphate pathway and/or an ability to synthesize dimethylallyl diphosphate via a mevalonate pathway, and the bacterium belongs to the genus Escherichia, Pantoea, Synechocystis, or Corynebacterium, and a 2-ketogluconate formation pathway is blocked in the bacterium, and
- (ii) collecting linalool from the culture medium or the bacterium;
- wherein said bacterium expresses linalool synthase;
- and
- wherein said linalool synthase has a property selected from the group consisting of:
- (a) amino acid sequence of said linalool synthase has at least one motif represented by the following formula:
- DDX1[F/Y][D/Y]X2X3G (SEQ ID NO:
- 184), wherein D represents aspartic acid, F represents phenylalanine, Y represents tyrosine, G represents glycine, X1, X2, and X3 each independently represent an arbitrary amino acid, [F/Y] represents F or Y, and [D/Y] represents D or Y, and wherein the at least one motif is selected from the group consisting of:
- a combination in which X1 is I, [F/Y] is F, [D/Y] is D, X2 is V, and X3 is Y;
- a combination in which X1 is I, [F/Y] is F, [D/Y] is D, X2 is V, and X3 is Y;
- a combination in which X1 is I, [F/Y] is F, [D/Y] is D, X2 is V, and X3 is H;
- a combination in which X1 is I, [F/Y] is F, [D/Y] is D, X2 is T, and X3 is Y;
- a combination in which X1 is I, [F/Y] is F, [D/Y] is Y, X2 is V, and X3 is C;
- a combination in which X1 is I, [F/Y] is Y, [D/Y] is D, X2 is I, and X3 is Y;
- a combination in which X1 is I, [F/Y] is Y, [D/Y] is D, X2 is A, and X3 is Y;
- a combination in which X1 is I, [F/Y] is Y, [D/Y] is D, X2 is V, and X3 is Y;
- a combination in which X1 is V, [F/Y] is Y, [D/Y] is D, X2 is I, and X3 is Y;
- a combination in which X1 is V, [F/Y] is Y, [D/Y] is D, X2 is V, and X3 is F;
- a combination in which X1 is M, [F/Y] is Y, [D/Y] is D, X2 is I, and X3 is Y;
- and
- a combination in which X1 is F, [F/Y] is F, [D/Y] is D, X2 is V, and X3 is E,
- (b) said linalool synthase is native to Streptomyces clavuligerus, and
- (c) combinations thereof.
