Gene Information

Name : irbB (MGAS1882_0200)
Accession : YP_005410968.1
Strain : Streptococcus pyogenes MGAS1882
Genome accession: NC_017053
Putative virulence/resistance : Virulence
Product : prophage gene expression coactivator protein IbrB
Function : -
COG functional category : -
COG ID : -
EC number : -
Position : 177092 - 177622 bp
