A protein complex composed of actin and myosin; it is the essential contractile substance of muscle fiber, active with MgATP.
actomyosin/ac·to·my·o·sin/ (ak″to-mi´o-sin) the complex of actin and myosin occurring in muscle fibers.
A complex of actin, myosin, and associated proteins that is responsible for contraction in cells, especially muscle cells.
Actomyosin(1) A term which considers the molecular motors—actin and myosin—as a single functional unit
(2) A G actin-like contractile protein complex found in platelets which consists of actin and myosin in a actin:myosin ratio of 100:1—muscle has a ratio of 7:1—and which appears with platelet activation.
A protein complex composed of actin and myosin; the essential contractile substance of muscle fiber.
actomyosina protein formed by the interaction of ACTIN and MYOSIN. It is closely concerned with the process of MUSCLE contraction.
actomyosinsystem of actin filaments and myosin particles forming muscle fibres that interact causing muscle contraction (see muscle contraction)
the complex of actin and myosin constituting muscle fibers and responsible for the contraction and relaxation of muscle.
