Cell membrane-bound ecto-nucleoside triphosphate diphosphohydrolases (NTPDases) are homooligomeric, with native quaternary structure required for maximal enzyme activity. In this study, we mutated lysine 79 in human ecto-nucleoside triphosphate diphosphohydrolase 3 (NTPDase3). The residue corresponding to lysine 79 in NTPDase3 is conserved in all known cell(More)
Chemical modification in combination with site-directed mutagenesis was used to identify a tyrosine residue responsible for the increase in ecto-nucleoside triphosphate diphosphohydrolase 3 (NTPDase3) nucleotidase activity after acetylation with a tyrosine-selective reagent, N-acetylimidazole. The NTPDase3 ATPase activity is increased more than the ADPase(More)
