Although the enzymatic properties of purified NM-2 motor fragments have been determined, the emergent properties of filament ensembles are unknown. Myofilaments are the filaments of myofibrils, constructed from proteins, principally myosin or actin.

The I-band is spanned by the titin molecule connecting the Z-line with a myosin filament. The region between two neighboring, parallel I-bands is known as the A-band and contains the entire length of single myosin myofilaments. Within the A-band is a region known as the H-band, which is the region not superimposed by actin myofilaments.

As we have mentioned on previous pages, the actin and myosin (Refer to exam q) Figure 1 shows a diagram of part of a muscle myofibril.

wt 175 kDa (Yokota et al. 1999) moves processively along actin filaments with a very high velocity (Tominaga et al. 2003).

Thick filaments consist primarily of the protein myosin. Each thick filament is approximately 15 nm in diameter, and each is made of several hundred molecules of myosin. A myosin molecule is shaped like a golf club, with a tail formed of two intertwined chains and a double globular head projecting from it at an angle. The flexed myosin then grabs the actin filament (shown in green and blue, from PDB entry 1atn ) and release of phosphate snaps it into the straight "rigor" form, as shown on the right (PDB entry 2mys ).

Effect of ageing of myosin on its ability to form synthetic filaments and on proteolysis of the LC2 light chain. Journal of Molecular Biology 1979, 134 (1) , 189-197.

We used a newly developed approach that allowed the use of physiological levels of ATP. Nonmusclemyosin 2 (NM-2) powers cell motility and tissue morphogenesis by assembling into bipolar filaments that interact with actin. Although the enzymatic properties of purified NM-2 motor fragments have been determined, the emergent properties of filament ensembles are unknown. Myofilaments are the filaments of myofibrils, constructed from proteins, principally myosin or actin. Types of muscle are striated muscle (such as skeletal muscle and cardiac muscle), obliquely striated muscle (found in some invertebrates), and smooth muscle.

Detection of small differences in actomyosin function using actin labeled with different Actin filament guidance on a chip: Toward high-throughput assays and

37 The repeating motif, representing a pair of myosin heads, has the appearance of a tilted J, which was interpreted as a pair of interacting myosin heads bent toward the The goal of this study was to prepare smooth muscle myosin (SMM) filaments containing a single head labeled with a quantum dot (QD) on the RLC. We show that when the RLC is coupled to a QD at Cys-108 and exchanged into SMM, subsequent filament assembly is severely disrupted. Thick filaments consist primarily of the protein myosin. Each thick filament is approximately 15 nm in diameter, and each is made of several hundred molecules of myosin. A myosin molecule is shaped like a golf club, with a tail formed of two intertwined chains and a double globular head projecting from it at an angle.
