摘要: Background The cluster of orthologous group COG2042 has members in all sequenced Eukaryota as well many Archaea. The cellular function these proteins ancient origin remains unknown. PSI-BLAST analysis does not indicate a possible link with even remotely-related that have been functionally or structurally characterized. As prototype among orthologs, SSO0551 protein from the hyperthermophilic archaeon Sulfolobus solfataricus was purified to homogeneity for biophysical characterization.
