Adenylate kinase is an enzyme that catalyzes the reaction ATP + AMP = 2ADP. It consists of two identical subunits, A (shown in blue) and B (shown in green). For simplicity's sake, only the A chain will be shown in consequent green links. Basic structural elements spinqualitylabelsall models Adenylate Kinase Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D Like many proteins, the secondary structure of adenylate kinase is consists of two elements: alpha-helices (shown in light green) and beta-sheets (shown in dark green). There are two types of secondary structure; the alpha-helices are highlighted in light green and the beta-sheets are highlighted in dark green. The hydrogen bonds are shown in yellow. They may be parallel or anti-parallel. Residues The protein consists of hydrophobic and hydrophilic residues, highlighted in gray and red, respectively. Water Accessibility The protein has certain water accessibility (water shown in blue, the enzyme shown in white), since water can't interact with all of it. Water also interacts with some of the internal residues. Waters are and aren't places. Ligand Some residues contact the ligand. Although not all of the highlighted residues contact the ligand, most of them do. Cationic side chains are shown in blue, whereas anionic side chains are shown in red. What kind of side chains interact with non-hydrolysable substrate. The catalytic residues are shown in green.
