This the C-terminal protein kinase domain of bacterial isocitrate dehydrogenase kinase/phosphatase (AceK) proteins (EC:2.7.1.116) [1,2]. It has a classic bi-lobe protein kinase fold with the ATP-binding cleft located at the interface between the two lobes. The N-terminal lobe comprises a twisted antiparallel beta-sheet of five strands and two alpha-helices. The C-terminal lobe is larger and mainly alpha-helical, with some stretches of antiparallel beta-strands [2].	Domain

This is the N-terminal regulatory domain of bacterial isocitrate dehydrogenase kinase/phosphatase (AceK) proteins (EC:2.7.1.116) [1,2]. It has an alpha-helical fold, with two long, parallel alpha-helices that form a large hairpin structure followed by two short, parallel alpha-helices forming a small hairpin segment. This domain is linked to the C-terminal kinase domain by a short (27 residues) alpha-helix [2].	Domain
