In enzymology, a furylfuramide isomerase () is an enzyme that catalyzes the chemical reaction
Hence, this enzyme has one substrate, (E)-2-(2-furyl)-3-(5-nitro-2-furyl)acrylamide, and one product, (Z)-2-(2-furyl)-3-(5-nitro-2-furyl)acrylamide.
This enzyme belongs to the family of isomerases, specifically cis-trans isomerases. The systematic name of this enzyme class is 2-(2-furyl)-3-(5-nitro-2-furyl)acrylamide cis-trans-isomerase. It has 2 cofactors: NAD+, and NADH.
