dc.description.abstractWe report here on the UV-induced vanadate-dependent cleavage of the alpha and beta heavy chains of the outer arm dynein from Chlamydomonas flagella. Both polypeptides are cleaved at a single site (termed the V1 site) by UV irradiation in the presence of Mg2+, ATP, and vanadate. The alpha chain yields fragments of Mr 290,000 and 190,000. Fragments of Mr 255,000 and 185,000 are obtained from the beta chain. Ultraviolet irradiation of the alpha and beta chains in the presence of vanadate and Mn2+ (but no nucleotide) induces cleavage of both molecules at sites (termed the V2 sites) distinct from the V1 sites. The single V2 site within the beta chain is located 75,000 daltons from the site of V1 cleavage within the Mr 255,000 V1 fragment. The alpha chain contains three distinct sites of V2 cleavage; all are located within the Mr 290,000 V1 fragment, 60,000, 90,000, and 100,000 daltons from the site of V1 cleavage. From these studies, we estimate the masses of the alpha and beta heavy chains to be 480,000 and 440,000 daltons, respectively.
