RT sequencing of parallel consortia.";
RL Submitted (SEP-2015) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Sigma factors are initiation factors that promote the
CC attachment of RNA polymerase to specific initiation sites and are then
CC released. {ECO:0000256|RuleBase:RU362124}.
CC -!- SIMILARITY: Belongs to the sigma-70 factor family.
CC {ECO:0000256|ARBA:ARBA00007788, ECO:0000256|RuleBase:RU362124}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:KPQ38615.1}.
