Advances in Metabolic Engineering for Biosynthesis of 5-Aminolevulinic Acid
5-aminolevulinic acid (5-ALA) is a naturally occurring, metabolically active non-proteinogenic amino acid that serves as a key precursor for the biosynthesis of heme, chlorophyll, and vitamin B12. Due to its high biological activity and versatile physiological functions, 5-ALA has been widely applied in agriculture,...
