actomyosin

 [ak″to-mi´o-sin]
the complex of actin and myosin constituting muscle fibers and responsible for the contraction and relaxation of muscle.
Actomyosin in muscle fibers. From Applegate, 2000.

ac·to·my·o·sin

(ak'tō-mī'ō-sin),
A protein complex composed of actin and myosin; it is the essential contractile substance of muscle fiber, active with MgATP.

actomyosin

(ăk′tə-mī′ə-sĭn)
n.
A complex of actin, myosin, and associated proteins that is responsible for contraction in cells, especially muscle cells.

actomyosin

[ak′təmī′əsin]

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.

ac·to·my·o·sin

(ak'tō-mī'ō-sin)
A protein complex composed of actin and myosin; the essential contractile substance of muscle fiber.

actomyosin

a protein formed by the interaction of ACTIN and MYOSIN. It is closely concerned with the process of MUSCLE contraction.

actomyosin

system of actin filaments and myosin particles forming muscle fibres that interact causing muscle contraction (see muscle contraction)

actomyosin

the complex of actin and myosin constituting muscle fibers and responsible for the contraction and relaxation of muscle.

The field of actomyosin expanded from muscle cells to non-muscle cells, including a variety of vertebrate and invertebrate cells.
This process is accomplished through the assembly and constriction of a contractile ring, a complex actomyosin network that remains poorly understood on the molecular level.
Also, the loss of Ca-ATPase activity due to oxidation of SH-groups on the actomyosin indicated aggregation or denaturation and this loss of activity increased considerably in the first month of storage.
