Protein

Cryptic beta-glucoside bgl operon antiterminator

Gene

bglG

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Mediates the positive regulation of the beta-glucoside (bgl) operon by functioning as a transcriptional antiterminator. This is an RNA-binding protein that recognizes a specific sequence located just upstream of two termination sites within the operon.

Post-translational modificationi

Phosphorylated and inactivated by BglF (eII-bgl). The degree of phosphorylation is dependent on the presence or absence of beta-glucosides which act as inducers of the operon expression. Addition of inducer result in the rapid dephosphorylation of BglG.

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.
