A new method for producing myosin subfragment-1
Biochemical and Biophysical Research Communications, 1972Abstract Myosin subfragment-1 (S1) was produced from myosin by digestion with papain while the myosin was “in situ” in a muscle fibril. S1 was extracted from the fibrils using Mg-PP i , and chromatographed on Sephadex G-200. This S1 had sedimentation and diffusion coefficients similar to those found for S1 by previous workers.

Interactions of myosin subfragment 1 isozymes with G-actin
Biochemistry, 1991The polymerization of G-actin by myosin subfragment 1 (S-1) isozymes, S-1(A1) and S-1(A2), and their proteolytically cleaved forms was studied by light-scattering, fluorescence, and analytical ultracentrifugation techniques. As reported previously, S-1(A1) polymerized G-actin rapidly while S-1(A2) could hardly promote the assembly reaction (Chaussepied

Ionization of reactive lysyl residue of myosin subfragment 1
Biochemistry, 1981The epsilon-NH2 groups of lysyl residues of myosin subfragment 1 belong to two classes on the basis of their reaction with 2,4,6-trinitrobenzenesulfonate: on reactive lysyl residue and 82 slow-reacting lysyl residues. The trinitrophenylation of the reactive lysyl residue is accompanied by a sharp decrease in the K+(EDTA)-activated ATPase of myosin ...

Preparation of Subfragment-1 from Abalone Smooth Muscle Myosin
The Journal of Biochemistry, 1988Myosin subfragment-1 (S1), which has one heavy chain (HC) (93 kDa) and two light chains (LC1 and LC2), was prepared by papain digestion of myosin from abalone-smooth muscle in the presence of Ca2+. The Ca-sensitivity of abalone S1 itself was not lost completely (about 30%).

Binding between maleimidobenzoyl-G-actin and myosin subfragment 1
Biochemistry, 1992It is well known that the structural interactions between S-1 moieties of myosin molecules ("cross bridges") and actin molecules in polymerized ("F") form are thought to underlie muscle contraction. It is surmised that such interactions are unitary (actin:S-1 = 1:1), but actual demonstration thereof is handicapped by intrinsic properties of the ...

Intramolecular cross-linking of myosin subfragment 1 with bimane
Biochemistry, 1987We previously showed that the fluorescent inter-thiol cross-linker dibromobimane (DBB) [Kosower, N. S., Kosower, E. M., Newton, G. L., & Ranney, H. M. (1979) Proc. Natl. Acad. Sci. U.S.A. 76, 3382-3386] cross-links two [50 and 20 kilodaltons (kDa)] of the three major fragments of myosin subfragment 1 (S-1); on intact S-1, DBB quenches tryptophans and ...
