Channel-Guided Engineering of Tryptophan Synthase β-Subunit for High-Level Biosynthesis of the Garlic Bioactive Compound S-Allyl- l -Cysteine
S-Allyl-l-cysteine (SAC) is a bioactive organosulfur compound from aged garlic that has attracted considerable interest for its health-promoting properties. Here, we developed a channel-guided engineering strategy to enhance SAC biosynthesis using the β-subunit of tryptophan synthase (TrpB). Genome mining guided by c...
