Overview

Name   comR   Type   Regulator
Locus tag   SSU_RS00330 Genome accession   NC_012925
Coordinates   55420..56319 (+) Length   299 a.a.
NCBI ID   WP_012774888.1    Uniprot ID   A0A116VRL0
Organism   Streptococcus suis P1/7     
Function   activate transcription of comX   
Competence regulation

Function

Induction of competence was dependent on ComX, a sigma factor that controls the streptococcal late competence regulon, extracellular addition of a comX-inducing peptide (XIP), and ComR, a regulator of comX. XIP was identified as an N-terminally truncated variant of ComS.
