Detailed information    

experimental Experimentally validated

Overview


Name   hapR   Type   Regulator
Locus tag   ABDM36_RS11380 Genome accession   NZ_CP157384
Coordinates   2522280..2522891 (+) Length   203 a.a.
NCBI ID   WP_000340098.1    Uniprot ID   B2CKP3
Organism   Vibrio cholerae C6706     
Function   regulate expression of competence genes   
Competence regulation

Function


Expression of all three genes in a ΔhapR and a ΔcytR mutant was approximately as low as in the strains lacking constitutive TfoX, which suggested that not only comEA, but also chiA-1, and pilA are positively regulated by both HapR and CytR.
