Fig. 7. Mass spectra and retention index of the hydroxylated sesquiterpene generated by PmSTS mutants L454G and L454A. NIST library mass spectra of (A) sesquicineole, (B) cis-sesquisabinene hydrate, (C) trans-sesquisabinene hydrate, and (D) α-bisabolol are shown at bottom of each respective sample mass spectra.
