Ta0938 is a protein of unknown function however the structure has been determined. The protein has a novel fold and a putative Zn-binding motif. The structure has two different parts, one region contains a beta sheet flanked by two alpha helices and the other contains a bundle of loops which contain all cysteines in the protein [1].
