Collection of regulogs for TrpR transcription factor family

General statistics
TF regulogs 16
TF regulons 105
TF binding sites 253

TrpR family of transcription factors includes repressors of the tryptophan biosynthesis genes in Gammaproteobacteria. Tryptophan itself works as corepressor of TrpR [16740930]. When tryptophan concentration in the cell is sufficient, TrpR repressor binds and blocks operator regions of target genes [16553875]. TrpR repressors are composed of a characteristic domain (PF01371) containing an HTH DNA binding motif [21553830].
