RT "Complete genome sequence of Novosphingobium guangzhouense SA925(T).";
RL Submitted (MAY-2016) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Participates in both transcription termination and
CC antitermination. {ECO:0000256|HAMAP-Rule:MF_00945}.
CC -!- SUBUNIT: Monomer. Binds directly to the core enzyme of the DNA-
CC dependent RNA polymerase and to nascent RNA. {ECO:0000256|HAMAP-
CC Rule:MF_00945}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00945}.
CC -!- SIMILARITY: Belongs to the NusA family. {ECO:0000256|HAMAP-
CC Rule:MF_00945}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
