CC -!- FUNCTION: Necessary for efficient RNA polymerase transcription
CC elongation past template-encoded arresting sites. The arresting sites
CC in DNA have the property of trapping a certain fraction of elongating
CC RNA polymerases that pass through, resulting in locked ternary
CC complexes. Cleavage of the nascent transcript by cleavage factors such
CC as GreA or GreB allows the resumption of elongation from the new
CC 3'terminus. GreA releases sequences of 2 to 3 nucleotides.
CC {ECO:0000255|HAMAP-Rule:MF_00105}.
CC -!- SIMILARITY: Belongs to the GreA/GreB family. {ECO:0000255|HAMAP-
CC Rule:MF_00105}.
