Insights into the evolution of enzymatic specificity and catalysis: From Asgard archaea to human adenylate kinases.

Enzymatic catalysis is critically dependent on selectivity, active site architecture, and dynamics. To contribute insights into the interplay of these properties, we established an approach with NMR, crystallography, and MD simulations focused on the ubiquitous phosphotransferase adenylate kinase (AK) isolated from (OdinAK). belongs to the Asgard archaeal phylum that is believed to be the closest known ancestor to eukaryotes.
