HrtR

The interaction of heme iron with HrtR is non-covalent, six-coordinated, and involves two histidines, HIS-72 and HIS-149 HrtR specifically binding to the 15-NT palindrome sequence in the hrtRBA promoter region, which is required for hrtRBA inhibition Hrtr-dna binding is abolished by heme addition, which activates the expression of the HRTB-HRTA (HrtBA) transporter in vitro and in vivo. The use of HrtR as an intracellular heme sensor appears to be conserve in many symbiotic bacteria.[1]
