Metabolic Engineering of Saccharomyces cerevisiae for High-Level Production of l-Pipecolic Acid from Glucose

l-Pipecolic acid (L-PA), an essential chiral cyclic nonprotein amino acid, is gaining prominence in the food and pharmaceutical sectors due to its wide-ranging biological and pharmacological properties. Historically, L-PA has been synthesized chemically for commercial purposes. This study introduces a novel and efficient microbial production method for L-PA using engineered strain
