Catalysis of the reaction: a nucleoside triphosphate + H2O = nucleoside diphosphate + phosphate. Catalysis of movement along a polymeric molecule such as a microfilament or microtubule, coupled to the hydrolysis of a nucleoside triphosphate. Catalysis of movement along a microfilament, coupled to the hydrolysis of a nucleoside triphosphate (usually ATP). Catalysis of movement along a microfilament towards the plus end, coupled to the hydrolysis of a nucleoside triphosphate (usually ATP). The plus end of an actin filament is the end that preferentially adds actin monomers. Catalysis of movement along a microfilament towards the minus end, coupled to the hydrolysis of a nucleoside triphosphate (usually ATP). The minus end of an actin filament is the end that does not preferentially add actin monomers.
