Stabilization of a primary loop in myosin subfragment 1 with a fluorescent crosslinker.
نویسندگان
چکیده
A bifunctional fluorescent alkylating agent, dibromobimane, has been used to stabilize a preexisting primary loop in myosin subfragment 1 (S-1). The crosslink achieved joins Cys-707 (called sulfhydryl group "SH1") of the 20-kDa domain (formerly called "20K" domain) with a thiol of the 50-kDa domain and seems to place the dibromobimane near the ATP-perturbable tryptophan.

Parking problem and negative cooperativity of binding of myosin subfragment 1 to F-actin.
Previously we provided evidence that myosin subfragment 1 (S1) can bind either one (state 1) or two actin monomers (state 2) in solution and in muscle fiber. Here we present results of the kinetics study of binding of S1 to F-actin labeled with fluorescent dye pyrene. A transition from state 1 to state 2 depends on probability that the second actin is free, which is high when molar ratio of S1/...
متن کاملRegulation of the actin-activated MgATPase activity of Acanthamoeba myosin II by phosphorylation
It had been proposed previously that only filamentous forms of Acanthamoeba myosin II have actin-activated MgATPase activity and that this activity is inhibited by phosphorylation of up to four serine residues in a repeating sequence in the C-terminal nonhelical tailpiece of the two heavy chains. We have reinvestigated these issues using recombinant WT and mutant myosins. Contrary to the earlie...

The hydrophobic fluorescent dye 3-[4-(3-phenyl-2-pyrazolin-1-yl)benzene-1-sulfonylamido]phen ylboronic acid (PPBA) stoichiometrically binds to myosin subfragment-1 (S-1) with a dissociation constant (Kd) of 26 microns. Upon addition of nucleotides to the complex of S-1 with PPBA, the PPBA-binding site is converted to a more firm hydrophobic pocket accompanied by a large fluorescence change. For...

Fluorescence polarization measurements were used to study changes in the orientation and order of different sites on actin monomers within muscle thin filaments during weak or strong binding states with myosin subfragment-1. Ghost muscle fibers were supplemented with actin monomers specifically labeled with different fluorescent probes at Cys-10, Gln-41, Lys-61, Lys-373, Cys-374, and the nucleo...
متن کاملMyosin subfragment binding for the localization of actin-like microfilaments in cultured cells. A light and electron microscope study
Fluorescein-labeled heavy meromyosin subfragment-1 (F-S-1) has been purified by ion exchange chromatography and characterized in terms of its ability to bind specifically to actin. F-S-1 activates the Mg++-adenosine triphosphatase activity of rabbit skeletal muscle actin and decorates actin as shown by negative stains and thin sections of rabbit actin and rat embryo cell microfilament bundles, ...
