Chains	Enzyme Name	Description	Catalytic Residues
B	nucleoside-diphosphate kinase M-CSA #150	Nucleoside diphosphate kinase (NDP kinase) is responsible for phosphorylating non-adenine nucleoside diphosphates. The phosphate donor is usually ATP, but the diphosphate nucleotide substrate is non-specific for either base or ribose / deoxyribose. The mechanism of nucleotide binding is different from that of most other phoshokinases and nucleotide binding proteins which use a parallel beta-sheet, NDP using an anti-parallel beta-sheet. NDPK from Dictyostelium discoideum is used as a model because it is particularly easy to crystallise.
