Enzymes from Fungal and Plant Origin Required for Chemical Diversification of Insecticidal Loline Alkaloids in Grass-Epichloë Symbiota
Figure 2
Enrichment of deuterated N-acetylnorloline (NANL) from application of tetradeuterated exo-1-acetemidopyrrolizidine ([2H4]AcAP) to loline alkaloid producing culture.
Shown are (A) GC-MS total ion chromatogram, (B) mass spectrum at retention time 13.948 and (C) 13.921 min, and (D) proposed scheme of [2H4]NANL formation from [2H4]AcAP.
