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
|
Like many proteins, the of adenylate kinase consists of two elements: alpha-helices (shown in light green) and beta-sheets (shown in dark green). Non-repetitive structural elements are shown in light blue/gray. In addition to the regular hydrogen bonding that causes the secondary structure of the protein, additional is present in the backbone of adenylate kinase (shown in yellow), which also contributes to the overall stability/folding of the molecule. A additional, significant factor in the structural stability/folding of the molecule is the polarity of the amino acid residues. The (nonpolar) residues are shown in gray, while the (polar/charged) residues are shown in red.
Water Accessibility
The protein has certain (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 . Waters are and aren't places.
Ligand
Some . 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 are shown in green.
