CC   -!- FUNCTION: Facilitates transcription termination by a mechanism that
CC       involves Rho binding to the nascent RNA, activation of Rho's RNA-
CC       dependent ATPase activity, and release of the mRNA from the DNA
CC       template. {ECO:0000255|HAMAP-Rule:MF_01884}.
CC   -!- SUBUNIT: Homohexamer. The homohexamer assembles into an open ring
CC       structure. {ECO:0000255|HAMAP-Rule:MF_01884}.
CC   -!- SIMILARITY: Belongs to the Rho family. {ECO:0000255|HAMAP-
CC       Rule:MF_01884}.
