ATP + AMP = 2 ADP
mechanism

ATP + AMP = 2 ADP
binding of ATP induces a dynamic equilibrium in which the ATP binding motif populates both the open and the closed conformations with almost equal populations. A similar scenario is observed for AMP binding, which induces an equilibrium between open and closed conformations of the AMP binding motif. Simultaneous binding of AMP and ATP is required to force both substrate binding motifs to close cooperatively. Unidirectional energetic coupling between the ATP and AMP binding sites
ATP + AMP = 2 ADP
coarse-grained models and nonlinear normal mode analysis. Intrinsic structural fluctuations dominate LID domain motion, whereas ligand-protein interactions and local unfolding are more important during NMP domain motion. LID-NMP domain interactions are indispensable for efficient catalysis. LID domain motion precedes NMP domain motion, during both opening and closing, providing mechanistic explanation for the observed 1:1:1 correspondence between LID domain closure, NMP domain closure, and substrate turnover
ATP + AMP = 2 ADP
induced-fit and change between open and closed conformation, random Bi-Bi reaction mechanism, the conformational change of the ADK enzyme very much follows two parallel stepwise pathways as a functional requirement for the double substrate catalysis

pfSMCnbd possesses reverse adenylate kinase activity. In adenylate kinase reactions, ATP binds to its canonical binding site while AMP binds to the Q-loop glutamine and a hydration water of the Mg2+ ion. Furthermore, mutational analysis indicates that adenylate kinase reaction occurs in the engaged pfSMCnbd dimer and requires the Signature motif for phosphate transfer

the cystic fibrosis transmembrane conductance regulator (CFTR) has adenylate kinase activity as an ABC adenylate kinase. ATP enables CFTR photolabeling by 8-N3-AMP, and AMP increases 8-N3-ATP photolabeling at ATP-binding site 2. AMP interacts with CFTR in an ATP-dependent manner and alters ATP interaction with the adenylate kinase active center ATP-binding site. Two other ABC proteins, Rad50 and a structural maintenance of chromosome protein, also have adenylate kinase activity. All three ABC adenylate kinases bind and hydrolyze ATP in the absence of other nucleotides

the cystic fibrosis transmembrane conductance regulator (CFTR) has adenylate kinase activity as an ABC adenylate kinase. ATP enables CFTR photolabeling by 8-N3-AMP, and AMP increases 8-N3-ATP photolabeling at ATP-binding site 2. AMP interacts with CFTR in an ATP-dependent manner and alters ATP interaction with the adenylate kinase active center ATP-binding site. Two other ABC proteins, Rad50 and a structural maintenance of chromosome protein, also have adenylate kinase activity. All three ABC adenylate kinases bind and hydrolyze ATP in the absence of other nucleotides
