NMR solution structure of the putative cation transport regulator ChaB
Overview
BACKGROUND: ChaB is a putative regulator of ChaA, a Na+/H+ antiporter that also has Ca+/H+ activity in E. coli. ChaB contains a conserved 60-residue region of unknown function found in other bacteria, archaeabacteria and a series of baculoviral proteins. As part of a structural genomics project, the structure of ChaB was elucidated by NMR spectroscopy. RESULTS: The structure of ChaB is composed of 3 alpha-helices and a small sheet that pack tightly to form a fold that is found in the cyclin-box family of proteins. CONCLUSION: ChaB is distinguished from its putative DNA binding sequence homologues by a highly charged flexible loop region that has weak affinity to Mg2+ and Ca2+ divalent metal ions.
