This entry represents the N-terminal domain of the Transcriptional repressor NrdR and similar sequences, which is a zinc beta-ribbon domain, followed by an ATP-cone domain (Pfam:PF03477) [1]. These proteins negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR-boxes. This domain harbors two conserved CxxC motifs that coordinate a zinc ion, and binds to the highly conserved NrdR boxes [1].
