Research Abstract |
Class II myosins have conserved Leu-Leu sequence at the beginning of the tail domain. When I deleted the Leu-Leu, the actin activated ATPase activity dropped significantly while its motility was almost the same as that of the wild type myosin.Results of stopped flow measurements suggested that the loss of Leu-Leu impairedcooperative interaction of the two heads of myosin with actin filaments.
