Detailed information NTG0000458

Experimentally validated

Overview

• Name: comR
• Type: Regulator
• Locus tag: SSUD9_RS00355
• Genome accession: NC_017620
• Coordinates: 59566..60483 (+)
• Length: 305 a.a.
• NCBI ID: WP_002935296.1
• Uniprot ID: -
• Organism: Streptococcus suis D9
• 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.
