'''STRUCTURE OF A MUTANT ADENYLATE KINASE LIGATED WITH AN ATP-ANALOGUE SHOWING DOMAIN CLOSURE OVER ATP'''<br />


==Overview==
==STRUCTURE OF A MUTANT ADENYLATE KINASE LIGATED WITH AN ATP-ANALOGUE SHOWING DOMAIN CLOSURE OVER ATP==
Structural studies on unligated and ligated adenylate kinases have shown that two domains, LID and NMPbind, close over the bound substrates, ATP and AMP, respectively. These motions can be, but need not be independent from each other. Up to now, the known structures display only the states "both domains open", "both closed" and "NMP bind closed". In spite of numerous cocrystallization attempts with ATP, a crystalline state "LID closed" has not yet been produced. These experiences suggested that LID closure depends on a bound AMP molecule, in contrast to enzyme kinetic studies indicating a random-bi-bi mechanism. Using an inactive mutant of yeast adenylate kinase together with the ATP analogue AMPPCF2P, however, we have now crystallized an adenylate kinase in the LID closed state. The structure was established at 2.36 A resolution; it indicates that the domain motions occur largely independent from each other in agreement with the kinetic studies. As a side-result, we report the protein environment of the fluorine atoms of the bound ATP analogue.

Function

KAD2_YEAST Catalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. Plays an important role in cellular energy homeostasis and in adenine nucleotide metabolism. Adenylate kinase activity is critical for regulation of the phosphate utilization and the AMP de novo biosynthesis pathways.[HAMAP-Rule:MF_03168][1] [2] [3]
