title: Nucleoside triphosphate specificity of firefly luciferase.
abstract: Twelve naturally occurring nucleoside triphosphates have been examined as substrates and inhibitors of the light-producing reaction of firefly luciferase. Deoxyadenosine 5'-triphosphate was 1.7% as effective relative to ATP as a substrate, whereas all others tested were less than 0.1% as effective as ATP. At concentrations normally present in mammalian cell extracts no interference with ATP measurements results from these nucleotides.
