Myosin super relaxed state
WebMyosin that is not actively cycling resides in a super relaxed state (SRX) , associated with a folded-back conformation not available for actin interaction. Biochemical and biophysical … Webmyosin: [noun] a fibrous globulin of muscle that can split ATP and that reacts with actin in muscle contraction to form actomyosin.
