1H, 13C, and 15N resonance assignments of NmtR, a Ni(II)/Co(II) metalloregulatory protein of Mycobacterium tuberculosis
- 202 Downloads
NmtR is a Ni(II)/Co(II)-specific repressor expressed in Mycobacterium tuberculosis, which regulates the transcription of a membrane transporter proposed to mediate cytoplasmic Ni(II)/Co(II) efflux. Here we report the backbone and side chain resonance assignments of the apo-NmtR and the backbone assignments of Ni(II)-bound form of NmtR.
