While a general consensus exists about the biochemical mechanism that underlies the initiation step of SM contraction,4 the subsequent phase concerning stress maintenance appears less clear. Active stress in a variety of intact SM preparations can be maintained independent of phosphorylation.811-15 Thus, phosphorylation of SM myosin correlates better with the shortening velocity of SM tissue.'6 It has been suggested that a second Ca'+-dependent regulatory mechanism could be involved in the
