== Publication Abstract from PubMed == | |||
TT1426, from Thermus thermophilus HB8, is a conserved hypothetical protein with a predicted phosphoribosyltransferase (PRTase) domain, as revealed by a Pfam database search. The 2.01 A crystal structure of TT1426 has been determined by the multiwavelength anomalous dispersion (MAD) method. TT1426 comprises a core domain consisting of a central five-stranded beta sheet surrounded by four alpha-helices, and a subdomain in the C terminus. The core domain structure resembles those of the type I PRTase family proteins, although a significant structural difference exists in an inserted 43-residue region. The C-terminal subdomain corresponds to the "hood," which contains a substrate-binding site in the type I PRTases. The hood structure of TT1426 differs from those of the other type I PRTases, suggesting the possibility that TT1426 binds an unknown substrate. The structure-based sequence alignment provides clues about the amino acid residues involved in catalysis and substrate binding. | TT1426, from Thermus thermophilus HB8, is a conserved hypothetical protein with a predicted phosphoribosyltransferase (PRTase) domain, as revealed by a Pfam database search.
