In enzymology, beta-nitroacrylate reductase () is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are 3-nitropropionic acid and oxidised nicotinamide adenine dinucleotide phosphate (NADP<sup>+</sup>). Its products are 3-nitroacrylic acid, reduced NADPH, and a proton.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 3-nitropropanoate:NADP+ oxidoreductase.
