Mechanosensitive Self-Assembly of Myosin II Minifilaments [PDF]

Phys. Rev. E 101, 022402 (2020), 2019
Self-assembly and force generation are two central processes in biological systems that usually are considered in separation. However, the signals that activate non-muscle myosin II molecular motors simultaneously lead to self-assembly into myosin II minifilaments as well as progression of the motor heads through the crossbridge cycle.

Molecular motors robustly drive active gels to a critically connected state

, 2013
Living systems often exhibit internal driving: active, molecular processes drive nonequilibrium phenomena such as metabolism or migration. Active gels constitute a fascinating class of internally driven matter, where molecular motors exert localized ...

A Python based automated tracking routine for myosin II filaments [PDF]

, 2020
The study of motor protein dynamics within cytoskeletal networks is of high interest to physicists and biologists to understand how the dynamics and properties of individual motors lead to cooperative effects and control of overall network behaviour.

Electrode measurements of the net charge on muscle proteins [PDF]

, 1997
Electrode techniques for measuring Donnan potentials in protein solutions were studied and applied to elucidate the effect of methylation on the net charge of heavy meromyosin (HMM) and the effect of Ca2+ on the net charge of the thin filament proteins.

Dynamics, CO depletion, and deuterium fractionation of the dense condensations within the fragmented prestellar core Orion B9-SMM 6 [PDF]

, 2013
We present APEX observations of C17O(2-1), N2H+(3-2), and N2D+(3-2) towards the subfragments inside the prestellar core SMM 6 in Orion B9. We combined these spectral line data with our previous SABOCA 350-{\mu}m dust continuum map of the source. The subfragments are characterised by subsonic internal non-thermal motions ({\sigma}NT~0.5cs), and most of ...

Myofibrillar protein degradation patterns and structural changes in skeletal muscle from electrically stimulated Bos taurus and Bos indicus crossbred cattle [PDF]

, 1995
Degradation of titin, nebulin, desmin and troponin-T, structural changes in nonstimulated (NS) and electrically stimulated (ES) bovine skeletal muscle and comparison of these changes in Angus x Jersey (AxJ) cattle (Bos taurus cross) with the changes in ...

Interaction of AMP-aminohydrolase with myosin and its subfragments.

Journal of Biological Chemistry, 1977
We have shown that purified rabbit skeletal muscle AMP-aminohydrolase binds to rabbit muscle myosin, heavy meromyosin, and Subfragment 2 but does not bind to light meromyosin nor to Subfragment 1. The dissociation constant for binding to myosin was determined to be 0.14 muM.

Human embryonic myosin heavy chain cDNA Interspecies sequence conservation of the myosin rod, chromosomal locus and isoform specific transcription of the gene [PDF]

A 3.6 kilobase cDNA clone coding for the human embryonic myosin heavy chain has been isolated and characterized from an expression library prepared from human fetal skeletal muscle.

Identification of functional differences between recombinant human α and β cardiac myosin motors [PDF]

, 2012
The myosin isoform composition of the heart is dynamic in health and disease and has been shown to affect contractile velocity and force generation. While different mammalian species express different proportions of α and β myosin heavy chain, healthy ...

Sliding Mechanism for Actin Myosin System [PDF]

INFORMATION, VOL.6 (2003)187-196, 2003
Based on the Stochastic Inclined Rods Model (SIRM) proposed by H. Matsuura and M. Nakano, we study the microscopic motion of actin myosin system including the motion of the G-actin. Our model is composed of an inclined spring (rod), a myosin head, a myosin filament and G-actins.
