Fig. 2: Structures of human NCC complexed with indapamide, chlorthalidone, and hydrochlorothiazide.

a, b Overall structure of NCC bound with indapamide shown in map (a) and ribbon diagram (b). c, d overall structure of NCC bound with chlorthalidone shown in map (c) and ribbon diagram (d). e, f Overall structure of NCC bound with hydrochlorothiazide shown in map (e) and ribbon diagram (f). Two NCC subunits are colored-coded blue and khaki. ATP, phosphoacceptors, indapamide, hydrochlorothiazide, and chlorthalidone are highlighted. The N-terminal phosphoregulatory region is shown in cyan with the phosphorylation sites highlighted in red.
