Crystal Structure of Thermus aquatics RNA Polymerase SigmaA Subunit Region 4 Bound to-35 Element DNACrystal Structure of Thermus aquatics RNA Polymerase SigmaA Subunit Region 4 Bound to-35 Element DNA

Structural highlights

1ku7 is a 4 chain structure with sequence from Thermus aquaticus. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2.4Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

SIGA_THEAQ Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth.[HAMAP-Rule:MF_00963][1] [2]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
