Expressioni

Inductioni

Induced upon entry into stationary phase, this is controlled at least in part by the RpoS sigma factor.

Interactioni

Subunit structurei

Associates exclusively with the 30S subunit; there is 0.1 copy per ribosome in the exponential phase and 0.4 copies per ribosome in the stationary phase. This is also true for several other K12 derivatives and strain B/R.1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
