Abstract:

There are many kinds of amino acids in nature. In addition to the 20 kinds used in protein synthesis,a large number of amino acids are used to synthesize biologically active substances,which are widely used in food,medicine and other fields. Among them,the unnatural aromatic amino acid L-phenylglycine as an important component is widely used in the biosynthesis of β-lactam antibiotics such as penicillin,virginomycin S,and protomycin I. At present,L-phenylglycine is mainly synthesized by chemical methods,but this method has low synthesis yield,high pollution,and it is not easy to obtain monochiral compounds. Biosynthesis of L-phenylglycine has the advantages of mild reaction conditions and good product stereoselectivity,so it has received extensive attention. Through the analysis of the two biosynthetic pathways of L-phenylglycine,the screening of relevant enzymes required for synthesis and the balance regeneration of cofactors,etc.,A synthetic route with acetophenone acid,mandelic acid and L-phenylalanine as substrates was gradually formed.This article mainly reviews the biosynthetic pathways and biosynthetic strategies of L-phenylglycine,and provides researchers with optimization directions,with a view to providing a theoretical reference for efficient industrial biosynthesis of L-phenylglycine.

Key words: L-phenylglycine, Biosynthesis, Synthetic strategy
