Identification of Key Residues for Enzymatic Carboxylate Reduction

Frontiers in Microbiology, 2018
Carboxylate reductases (CARs, E.C. 1.2.1.30) generate aldehydes from their corresponding carboxylic acid with high selectivity. Little is known about the structure of CARs and their catalytically important amino acid residues.
