The SO2946 protein consists of a short helical N-terminal domain and a large C-terminal domain with the "jelly-roll" topology. The protein assembles into a propeller consisting of three C-terminal blades arranged around a central core formed by the N-terminal domains. The function of SO2946 could not be inferred from the sequence since the protein represents an orphan with no sequence homologs, but the protein's structure bears a fold similar to that of proteins containing carbohydrate-binding modules. Features such as fold conservation, the presence of a conserved groove and a metal binding region are indicative that SO2946 may be an enzyme and could be involved in binding carbohydrate molecules. Structure of SO2946 orphan from Shewanella oneidensis shows "jelly-roll" fold with carbohydrate-binding module.,Nocek B, Bigelow L, Abdullah J, Joachimiak A J Struct Funct Genomics. 2008 Dec;9(1-4):1-6.
