Domain

Transcription regulator IclR, N-terminal (IPR005471)

Short name: Tscrpt_reg_IclR_N

Domain relationships

None.

Description

The many bacterial transcription regulation proteins which bind DNA through a 'helix-turn-helix' motif can be classified into subfamilies on the basis of sequence similarities. One of these subfamilies, called 'iclR', groups several proteins including:

  • gylR, a possible activator protein for the gylABX glycerol operon in Streptomyces.
  • iclR, the repressor of the acetate operon (also known as glyoxylate bypass operon) in Escherichia coli and Salmonella typhimurium.

These proteins have a Helix-Turn-Helix motif at the N terminus that is similar to that of other DNA-binding proteins [PMID: 1840643].
