Structure of CorB and orthologue CNNM2; A Structure of the pentamer Methanoculleus thermophilus Cobalt of resistance CorB MtCorB (PDB: 7M1T) in complex with Mg2+-ATP (purple spheres, left panel) with one monomer highlighted. Right panel: zoom in on residues of the CBS domain that bind MgATP. Residues highlighted are homologues to human Cyclin M2 (hCNNM2) associated hypomagnesaemia, seizure, intellectual disability (HSMR) syndrome Thre568Ile (MtCorB-p.Thr313) and hCNNM4 associated Jalili syndrome Arg407Leu (Mt-CorB-p.Arg235). B Schematic depiction of the monomer of CorB (upper panel) and CNNM2 (bottom panel) using same colours as in A to reflect the approximate structure and location. The schematic structure of the human homologue has been depicted, which has been based on the estimated structure using homology modelling of CorB, as illustrated in Chen et al. (2021) [101]
