This domain is found at the C-terminal end DEAD box helicase Hera from Thermus thermophilus. This entry represents the RNA binding domain, which is located C-terminal to the dimerisation domain Pfam:PF21591. This domain is responsible for binding of Hera to 23S rRNA. It consists of a central four-stranded beta-sheet, flanked by an alpha-helix, and a long loop connecting beta-strands 3 and 4 that replaces helix alpha2 present in canonical RNA recognition motif (RRM) [1,2].
