4.2.3.9	Y92F	100fold reduction in kcat, 50fold decrease in KM, resulting in 2fold decrease in kcat/Km. The mutant enzyme produces (+)-aristolochene as 81% of the product, 7% (-)-valencene and 12% (S)-(-)-germacrene A	665301	
4.2.3.9	Y92F	reduction of the size of the side chain of residue 92 leads to the production of the alicyclic sesquiterpenes (E)-beta- and (E,E)-alpha-farnesene	644243	
4.2.3.9	Y92F	the mutant enzyme is approximately 0.1% as active as the nonmutated recombinant enzyme, the mutant releases significant amounts of germacrene A and also produces various amounts of a further five hydrocarbons of molecular weight 204, valencene, beta-(E)-farnesene, alpha-selinene, beta-selinene and selina-4,11-diene. The CD spectrum of the mutant enzyme is very similar to that of the wild-type enzyme	644242	
4.2.3.9	Y92V	reduction of the size of the side chain of residue 92 leads to the production of the alicyclic sesquiterpenes (E)-beta- and (E,E)-alpha-farnesene	644243	
4.2.3.9	Y92V	the mutant produces the alicyclic beta-(E)-farnesene as the major product	644241
