A bouquet of bacteria : Methylisoborneol ( 1 ) is a widely occurring volatile from bacteria and an undesirable flavor (off‐flavor) in the food industry. The analysis of isotopomers obtained by feeding isotopically labeled precursors to myxobacteria revealed the biosynthetic pathway to 1 . Geranylpyrophosphate (GPP) is alkylated by S ‐adenosylmethionine (SAM) and the product is cyclized to 1 . The methylation of GPP is unprecedented in nature.
