The interaction of the adenylate cyclase catalytic domain (AC) of the Bordetella pertussismajor exotoxin with its activator calmodulin (CaM) was studied by time-resolved fluorescence spectroscopy using three fluorescent groups located indifferent regions ofAC: tryptophan residues (W69 and W242), a nucleotide analogue (3¢-anthraniloyl-2¢-deoxyadenosine 5¢-triphosphate, Ant-dATP) and a cysteine-specific probe (acrylodan).
