Abstract
Mandelic acid and its derivatives are an important class of chemical synthetic blocks, which is widely used in drug synthesis and stereochemistry research. In nature, mandelic acid degradation pathway has been widely identified and analyzed as a representative pathway of aromatic compounds degradation. The most studied mandelic acid degradation pathway from Pseudomonas putida consists of mandelate racemase, S-mandelate dehydrogenase, benzoylformate decarboxylase, benzaldehyde dehydrogenase and downstream benzoic acid degradation pathways. Because of the ability to catalyze various reactions of aromatic substrates, pathway enzymes have been widely used in biocatalysis, kinetic resolution, chiral compounds synthesis or construction of new metabolic pathways. In this paper, the physiological significance and the existing range of the mandelic acid degradation pathway were introduced first. Then each of the enzymes in the pathway is reviewed one by one, including the researches on enzymatic properties and the applications in biotechnology as well as efforts that have been made to modify the substrate specificity or improving catalytic activity by enzyme engineering to adapt different applications. The composition of the important metabolic pathway of bacterial mandelic acid degradation pathway as well as the researches and applications of pathway enzymes is summarized in this review for the first time.
