Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe crystal structure of a hypothetical protein ST2348 (GI: 47118305) from the hyperthermophilic bacteria Sulfolobus tokodaii has been determined using X-ray crystallography. The protein consists of two CBS (cystathione beta synthase) domains, whose function has been analyzed and reported here. PSI-BLAST shows a conservation of this domain in about 100 proteins in various species. However, none of the close homologs of ST2348 have been functionally characterized so far. Structure and sequence comparison of ST2348 with human AMP-kinase gamma1 subunit and the CBS domain pair of bacterial IMP dehydrogenase is suggestive of its binding to AMP and ATP. A highly conserved residue Asp118, located in a negatively charged patch near the ligand binding cleft, could serve as a site for phosphorylation similar to that found in the chemotatic signal protein CheY and thereby ST2348 can function as a signal transduction molecule.
