a Strategy for modification of the shikimate pathway and MVA pathway to enhance precursor supply. The genes that are overexpressed are highlighted in green, and those knocked out are shown in gray. PP Pathway pentose phosphate pathway, PEP phosphoenolpyruvate, E4P D-erythrose-4-phosphate, DAHP 7P-2-dehydro-3-deoxy-D-arabino-heptonate, 4-HPP 4-hydroxy-phenylpyruvate, PPY phenylpyruvate, Tyr tyrosine, Phe phenylalanine, MVA pathway mevalonic acid pathway, HMG-CoA 3-hydroxy-3-methyl-glutaryl-CoA, FPP farnesyl pyrophosphate, GGPP geranylgeranyl diphosphate, IAA indole acetaldehyde, PAA phenylacetaldehyde, 4-HPAA 4-hydroxyphenylacetaldehyde, Tkl1 transketolase, Aro4 3-deoxy-D-arabino-heptulosonate-7-phosphate synthase, Aro7 chorismate mutase, Tyr1/TyrC cyclohexadienyl dehydrogenase, Aro10 phenylpyruvate decarboxylase, Aro8/Aro9 tyrosine aminotransferase, tHMG1 truncated 3-hydroxy-3-methyl-glutaryl reductase, CrtE geranylgeranyl diphosphate synthase. b Effect of stepwise optimization of shikimate pathway on HGA accumulation in YS-11. YS-11+Tyr indicates YS-11 cultured with exogenously addition of tyrosine. All values presented are the means of three biological replicates, and error bars represent standard deviations.
