Project Description
This project investigates the dual-bottleneck mechanism in cell-free psilocin biosynthesis. Using ODE modeling and molecular docking, we identified that yield is primarily constrained by SAM-dependent methylation (requiring a 2:1 Methionine:Trp ratio) and phosphatase-dependent dephosphorylation in bypass pathways. Optimization suggests that maintaining high PsiM activity and titrating phosphatase levels are critical for overcoming metabolic stalls at norbaeocystin and psilocybin.
