Protein

Transcriptional activator CadC

Gene

cadC

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Required for Pcad induction, a promoter upstream of cadBA that is responsible for the pH-regulated expression of CadA and CadB. Probably acts as an activating transcription factor.1 Publication

Expressioni

Inductioni

Induction requires low pH plus exogenous lysine as sensed by LysP as well as EF-P for translation. This requirement is reduced as the number of consecutive Pro residues in the protein is decreased.1 Publication

Similar proteinsi

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.
