== Function ==
[https://www.uniprot.org/uniprot/CAR_MYCMM CAR_MYCMM] Catalyzes the reduction of a wide range of aliphatic fatty acids (C6-C18) into their corresponding aldehydes, by using ATP for energy to drive the reaction. Can also reduce benzoate to benzaldehyde. Has a preference for NADPH over NADH as the electron donor.<ref>PMID:23248280</ref>

== Publication Abstract from PubMed ==
Carboxylic acid reductase (CAR) catalyzes the ATP- and NADPH-dependent reduction of carboxylic acids to the corresponding aldehydes. The enzyme is related to the nonribosomal peptide synthetases, consisting of an adenylation domain fused via a peptidyl carrier protein (PCP) to a reductase termination domain. Crystal structures of the CAR adenylation-PCP didomain demonstrate that large-scale domain motions occur between the adenylation and thiolation states. Crystal structures of the PCP-reductase didomain reveal that phosphopantetheine binding alters the orientation of a key Asp, resulting in a productive orientation of the bound nicotinamide. This ensures that further reduction of the aldehyde product does not occur. Combining crystallography with small-angle X-ray scattering (SAXS), we propose that molecular interactions between initiation and termination domains are limited to competing PCP docking sites. This theory is supported by the fact that (R)-pantetheine can support CAR activity for mixtures of the isolated domains. Our model suggests directions for further development of CAR as a biocatalyst.
