2.7.4.6 ATP + nucleoside diphosphate = ADP + nucleoside triphosphate isozyme NDPKB shows a ping-pong phospho-transfer mechanism, salt and nucleotide dependent NDPKB assembly is dynamic and requires its catalytic activity 691099 2.7.4.6 ATP + nucleoside diphosphate = ADP + nucleoside triphosphate many nucleoside diphosphates can act as acceptors, while many ribo- and deoxyribonucleoside triphosphates can act as donors - 2.7.4.6 ATP + nucleoside diphosphate = ADP + nucleoside triphosphate mechanism 642637, 642662, 642665, 642669, 642673 2.7.4.6 ATP + nucleoside diphosphate = ADP + nucleoside triphosphate mechanism, role of 3’-OH moiety of nucleotide 642672 2.7.4.6 ATP + nucleoside diphosphate = ADP + nucleoside triphosphate overview on mechanism 642682 2.7.4.6 ATP + nucleoside diphosphate = ADP + nucleoside triphosphate phosphoenzyme intermediate with 2-4 mol phosphate per mol of enzyme 642661 2.7.4.6 ATP + nucleoside diphosphate = ADP + nucleoside triphosphate ping pong mechanism with formation of an enzyme intermediate phosphorylated at His118 694346 2.7.4.6 ATP + nucleoside diphosphate = ADP + nucleoside triphosphate the catalytic mechanism involves a phosphoenzyme intermediate 642644, 642646, 642655, 642656 2.7.4.6 ATP + nucleoside diphosphate = ADP + nucleoside triphosphate the reaction catalyzed by NDK starts with the transfer of a phosphate from ATP to His117. ADP is then released and the acceptor nucleoside diphosphate is bound and phosphorylated. Nucleotide phosphates are coordinated by a network of basic Arg and His residues, and a polar Thr. All NDKs follow a ping-pong enzymatic mechanism involving a phosphorylated histidine residue in the active site 737374 2.7.4.6 ATP + nucleoside diphosphate = ADP + nucleoside triphosphate two-step ping-pong mechanism -, 660576
