This family has a novel fold known as a spiral beta-roll, consisting of a 15-stranded beta sheet wrapped around a single alpha helix. It forms dimers. It has some structural similarity to the E. coli lipoprotein localisation factors LolA, Swiss:P61316 and LolB, Swiss:P61320. Its structure suggests that it may have a role in glycolipid binding. Its genomic context supports a role in glycolipid metabolism [1].
