The stoichiometry of the components of arthropod thin filaments.

Abstract

Limulus thin filaments confer calcium sensitivity on calcium-independent myosins and contain in addition to actin and tropomyosin, three troponin components. The molar ratio of actin:tropomyosin:troponin sub-unit T (TN-T): troponin sub-unit C (TN-C) is approximately 7:1:1:1, as in vertebrates, but twice the amount of the troponin sub-unit I (TN-I) may be present. Arthropod troponin binds approximately 1 mole Ca/mol troponin, a significantly smaller amount than bound by vertebrate troponin.
