>TIGR01033 TIGR01033 conserved hypothetical protein TIGR01033; InterPro: IPR002876 This domain is found in bacteria, plants, and yeast proteins. It compromises the entire length or central region of most of the proteins in the family, all of which are hypothetical with no known function. The average length of this domain is approximately 230 amino acids long. The crystal structure of a conserved hypothetical protein, Aq1575, from Aquifex aeolicus has been determined. A structural homology search reveals that this protein has a new fold with no obvious similarity to those of other proteins of known three-dimensional structure. The protein reveals a monomer consisting of three domains arranged along a pseudo threefold symmetry axis. There is a large cleft with approximate dimensions of 10 A x 10 A x 20 A in the centre of the three domains along the symmetry axis. Two possible active sites are suggested based on the structure and multiple sequence alignment. There are several highly conserved residues in these putative active sites ..
