Data obtained from the CD-search using the prokaryotic protein sequences as queries. The -values shown in parentheses are data from the Pfam sequence searches. “ND” means not detected. The aa positions of alignments obtained in the Pfam sequence searches are not shown except the case of D1YLG5. Both searches were performed under the default conditions.
