The QueF monomer is made up of two ferredoxin-like domains aligned together with their beta-sheets that have additional embellishments. This subunit is composed of a three-stranded beta-sheet and two alpha-helices. QueF reduces a nitrile bond to a primary amine. The two monomer units together create suitable substrate-binding pockets [1].	Domain
