Carboxylic acid reductases (CARs) are an emerging biocatalyst platform for the synthesis of a diverse array of aldehydes from carboxylic acids, operating chemoselectively and under mild aqueous conditions. As such, there is growing interest in the industrial application of these enzymes, both for the synthesis of aldehyde end-products, which are particularly prevalent in the flavor and fragrance industries, and aldehyde intermediates in multi-enzyme cascades. This perspective aims to review recent developments in the applications of CARs with a focus on the challenges and considerations involved in their implementation, as well as potential solutions with a view to increased industrial utility.
