• PubMed Abstract: 
  

  Domain of unknown function 61 (DUF61) family proteins widely exist in archaea and the genes of DUF61 proteins in crenarchaea are in an operon containing two genes of box C/D RNA protein complexes. Here we report the solution NMR structure of DUF61 family member protein SSO0941, from the hyperthermophilic archaeon Sulfolobus solfataricus. SSO0941 has a rigid core structure and flexible N- and C-terminal regions as well as a negatively-charged independent C-terminal helix. The core structure consists of N- and C-terminal subdomains, in which the C-terminal subdomain shows significant structural similarity with several nucleic acid binding proteins. The structure of SSO0941 is the first representative structure of DUF61 family proteins.
