Detailed information    

experimental Experimentally validated

Overview

Name   comX/sigX   Type   Regulator
Locus tag   SSUD9_RS00080 Genome accession   NC_017620
Coordinates   16136..16606 (+) Length   156 a.a.
NCBI ID   WP_002936602.1    Uniprot ID   -
Organism   Streptococcus suis D9     
Function   activate transcription of late competence genes   
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.
