Proteins in this entry belong to the Formate-Nitrite Transporter (FNT) family and includes the nitrite transport protein NirC and formate channel FocA [1,2]. They have a pentameric architecture with structural similarity to aquaporins and glyceroporins, comprising a right-handed bundle of 6 transmembrane (TM) alpha-helices [1]. Proteins in this family transport the structurally related compounds, formate and nitrite.	Domain
