products description :
MAb to sigma Fecl subunit of E.coli RNA polymerase. Sigma Fecl is a 19 kDA subunit of the E.coli RNA polymerase. Sigma fecI is a 19kDa transcription factor of E.coli RNA polymerase. sigmaFecl is a 19kDa subunit of the E.coli RNA polymerase. Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor regulates the fec genes for iron dicitrate transport

ncbi summary :
Polyamine modulon. [More information is available at EcoGene: EG10291]. FecI (sigma19) was first described as a protein that regulated the expression of genes involved in the transport of ferric citrate ; later, it was determined as sigma factor based on similarities to a subgroup of sigma70 factors, and it binds to the fec transport gene promoter upstream fecA . [More information is available at EcoCyc: EG10291].
uniprot summary :
Function: Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor regulates the fec genes for iron dicitrate transport . Probable. Sequence similarities: Belongs to the sigma-70 factor family. ECF subfamily.
