Abstract: The a and b heavy chains of dynein from sea urchin sperm flagella undergo specific cleavage at the Vl site when irradiated with 365 nm UV light, MgATP, and vanadate. This specific photocleavage of dynein results in the scission of the a and fJ heavy chains of Hr 428,000 to form HUVl and LUVl cleavage peptides of Hx 228,000 and Hx 200, 000, respectively (Gibbons I. R., Lee-Eiford A., Mocz G., Phillipson C. A., Tang W. -J. Y., & Gibbons B. H. (1987) J. Biol. Chem. 262, 2780-2786). To investigate the effects of molecular oxygen on the cleavage reaction, two procedures for irradiation under anoxic conditions have been developed.
