RT "Dictyostelium myosin-5b is a conditional processive motor.";
RL J. Biol. Chem. 283:26902-26910(2008).
CC -!- FUNCTION: Processive motor protein that can move over long distances
CC along F-actin without disassociating; processiveness depends on high
CC physiological Mg(2+) concentrations. Presents a high actin affinity in
CC the presence of ADP, fast ATP hydrolysis, and a high steady-state
CC ATPase activity in the presence of actin that is rate limited by ADP
CC release. Physiological decrease of free Mg(2+) ions leads to an
CC increased rate of ADP release and shortening of the fraction of time it
CC spends in the strong acting binding states.
CC {ECO:0000269|PubMed:18650439}.
CC -!- SUBUNIT: Homodimer that associates with six light chains.
CC -!- SUBCELLULAR LOCATION: Contractile vacuole
CC {ECO:0000269|PubMed:18650439}.
CC -!- SIMILARITY: Belongs to the TRAFAC class myosin-kinesin ATPase
CC superfamily. Myosin family. {ECO:0000305}.
