benzaldehyde dehydrogenase (NAD+) activity
Definition
Target type: molecularfunction
Catalysis of the reaction: benzaldehyde + NAD+ + H2O = benzoate + NADH + H+. [EC:1.2.1.28]
Benzaldehyde dehydrogenase (NAD+) is a key enzyme in the metabolism of aromatic compounds, specifically in the oxidation of benzaldehyde to benzoate. This reaction is essential for the degradation of aromatic compounds in various organisms, including bacteria, fungi, and plants. The enzyme utilizes NAD+ as a cofactor, accepting electrons from the oxidation of benzaldehyde and reducing NAD+ to NADH. The catalytic mechanism involves the formation of a Schiff base intermediate between the enzyme and benzaldehyde, followed by hydride transfer from the benzaldehyde to NAD+. The resulting benzoate product is released from the enzyme, and the NADH molecule dissociates, ready to participate in other metabolic reactions. Benzaldehyde dehydrogenase (NAD+) activity is crucial for detoxification of aromatic compounds, providing a pathway for their breakdown and preventing their accumulation in cells. It also plays a vital role in various metabolic pathways, including the synthesis of aromatic amino acids, the degradation of lignin, and the production of important secondary metabolites.'
