Heme controls the structural rearrangement of its sensor protein mediating the hemolytic bacterial survival

Nishinaga et al. present structural characterization of the transcription regulator PefR from S. agalactiae in different states (apo-, DNAbound, heme-bound, CO-heme-bound and CN-heme-bound-PefRs). Structural comparison revealed that unique heme coordination controls structural rearrangement for the survival of the neonatal infection-causing hemolytic bacteria.
