The CorA family of divalent cation transporters utilizes Mg2+ and Co2+ as primary substrates. The molecular mechanism of its function, including ion selectivity and gating, has not been fully characterized. Recently we reported a new structure of a CorA homologue from Methanocaldococcus jannaschii, which provided novel structural details that offered the(More)
The present study was performed to compare glucocorticoid levels in obese KKA (y) and ob/ob mice with those in normal C57BL/6J mice, and the effect of high-fat diet on glucocorticoids in KKA (y) and ob/ob mice. Liver, mesenteric and epididymal adipose tissue corticosterone and 11-dehydrocorticosterone concentrations as well as circulating corticosterone(More)
CorA is a family of divalent cation transporters ubiquitously present in bacteria and archaea. Although CorA can transport both Mg(2+) and Co(2+) almost equally well, its main role has been suggested to be that of primary Mg(2+) transporter of prokaryotes and hence the regulator of Mg(2+) homeostasis. The reason is that the affinity of CorA for Co(2+) is(More)
