RNA-binding GUCT-like domain found in Thermus thermophilus heat resistant RNA-dependent ATPase (Hera) and similar proteins This subfamily corresponds to the Gu C-terminal (GUCT)-like domain of Hera and similar proteins. Thermus thermophilus Hera is a DEAD box helicase that binds fragments of 23S rRNA and RNase P RNA via its C-terminal domain. It contains a helicase core that harbors two RecA-like domains termed RecA_N and RecA_C, a dimerization domain (DD), and a C-terminal RNA-binding domain (RBD) that reveals a compact, RRM-like fold and shows sequence similarity with GUCT domain found in vertebrate RNA helicase II/Gualpha (RH-II/Gualpha), RNA helicase II/Gubeta (RH-II/Gubeta) and plant DEAD-box ATP-dependent RNA helicase 7 (RH7 or PRH75).
