Engineered biosynthetic pathways for pterostilbene starting from l-tyrosine in E. coli and the proposed ferulic acid biosynthetic pathway. TAL (tyrosine ammonia-lyase), CCL (p-coumarate: CoA ligase), STS (stilbene synthases), ROMT (resveratrol O-methyltransferases), p-coumarate 3-hydroxylase (C3H), COMT (caffeic acid methyltransferase). Bold arrows are genes used in this study
