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:0000256|ARBA:ARBA00024916, ECO:0000256|HAMAP-Rule:MF_00105,
CC       ECO:0000256|RuleBase:RU000556}.
CC   -!- SIMILARITY: Belongs to the GreA/GreB family.

CC       ECO:0000256|RuleBase:RU000556}.
CC   -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC       whole genome shotgun (WGS) entry which is preliminary data.
