Fig. 3: Structural comparison of AZG2 and AZG1.
From: Structural basis of cytokinin transport by the Arabidopsis AZG2
a Structural alignment of AZG2 and AZG1 (PDB code: 8IRL) in the apo state. AZG2 and AZG1 are colored purple and cyan, respectively. b Structural alignment of AZG2 and AZG1 protomer. Structural variations in the linker domain are indicated by dashed circles. c Cartoon representation of AZG2 in the side-view and top-view. A zoomed-in view of dimer interface in the extracellular domain of AZG2 is shown. The two protomers of AZG2 are colored red and blue, respectively. Residues at the interface are shown in sticks and colored yellow. d Cartoon representation of AZG1 (Protein Data Bank (PDB) accession code: 8IRL) in the side-view and top-view. A zoomed-in view of dimer interface in the extracellular domain of AZG1 is shown. The two protomers of AZG1 are colored cyan and orange, respectively. Residues at the interface are shown in sticks and colored yellow. Hydrogen bonds are shown in red dashed lines.
