Crystal structure of N-terminal domain of E. coli RssBCrystal structure of N-terminal domain of E. coli RssB

Structural highlights

3eod is a 1 chain structure with sequence from Escherichia coli K-12. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 1.75Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

RSSB_ECOLI Regulates the turnover of the sigma S factor (RpoS) by promoting its proteolysis in exponentially growing cells. Acts by binding and delivering RpoS to the ClpXP protease. RssB is not co-degraded with RpoS, but is released from the complex and can initiate a new cycle of RpoS recognition and degradation. In stationary phase, could also act as an anti-sigma factor and reduce the ability of RpoS to activate gene expression. Is also involved in the regulation of the mRNA polyadenylation pathway during stationary phase, probably by maintaining the association of PcnB with the degradosome.[HAMAP-Rule:MF_00958][1] [2] [3] [4] [5] [6]

Evolutionary Conservation

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