Skeletal Cubic, Lamellar, and Ribbon Phases of Bundled

Upon melting, all compounds start with lamellar LC phases, followed on heating by a rectangular columnar ribbon phase with c 2 mm symmetry. Unusually, a ribbon is a flat bundle of

Structural Insights into the Chaperone-Assisted Assembly of a

5 provides insights into the assem-bly mechanism of phage tail fiber assisted by an intermolecular chaperone. Structural analysis clearly shows that the role of chaperone is to initiate the...

Muscle Tissue | Basicmedical Key

The perimysium is a thin connective tissue layer that immediately surrounds each bundle of muscle fibers termed a fascicle (Figure 10–3). Each

Textile and Fashion Technology

Mercerisation under tension causes the fibre to become smoother, more regular and nearly cylindrical. The cross sectional shape of mercerised cotton is round to oval and the almost absent.

Hair bundles of cochlear outer hair cells are shaped to

We find that rows of V-shaped hair bundles have a considerably reduced resistance to crossflow, and that the biologically observed shapes of

Collagen fibril assembly: New approaches to unanswered questions

The fibres provide mechanical reinforcement, whilst the hydrogels can be loaded with biological agents to improve biocompatibility and allow fibre sliding. The relative length distribution of

Structure of the receptor-binding carboxy-terminal domain of

The six bacteriophage T7 tail fibers, homo-trimers of gene product 17, are thought to be responsible for the first specific, albeit reversible, attachment to Escherichia coli lipopolysaccharide.

The Spinal Cord Anatomy

The spinal cord is a cylindrical shaped bundle of nerve fibers that is connected to the brain at the brain stem. The spinal cord

The structure of Shigella virus Sf14 reveals the presence of two

OtherstructuresresolvedhereindicatethatSf14particleshavetwosets of whiskers, two types of tail fibers, a Mu-like baseplate, and a central tail needle bound to a terminal dome-shaped cap.

Nearly complete structure of bacteriophage DT57C reveals

Here, we present the structure of DT57C determined by cryo-EM, and an atomic model of the virus, which was further explored using all-atom molecular dynamics simulations.

Muscle myosin filaments: cores, crowns and couplings

Rather than having the myosin heads pointing in opposite directions in the two halves of a myosin filament as in bipolar filaments (Fig. 2b), in this case what was found was heads pointing in opposite

RBPseg: Toward a complete phage tail fiber structure atlas

Here, we introduce RBPseg, a method that combines monomeric ESMFold predictions with a structural- based domain identification approach, to divide tail fiber sequences into

Structures of the tailed bacteriophages that infect Gram-positive

Assembly of tail fibers from some bacteriophage requires the aid of an ''autochaperone'' as shown for the phi29 tail appendage . The precursor protein of the phi29 tail fiber contains an ATP

Phage tail fibre assembly proteins employ a modular structure to drive

The crystal structure of a complex between the tail fibre and tail fibre assembly (Tfa) protein of Escherichia coli phage Mu reveals the mechanisms by which Tfa regulates fibre assembly

The structure and properties of ribbon-shaped carbon fibers with high

The preferred orientation, morphology, and microstructure, as well as physical properties, of the ribbon-shaped carbon fibers were characterized. The results show that, the ribbon-shaped

Branched Lateral Tail Fiber Organization in T5-Like Bacteriophages

The virion of bacteriophage T5 consists of an isometric icosahedral T = 13 head, containing 105 k.b.p. of genomic DNA, and a long noncontractile tail with a single central tail fiber

11.1A: Overview of the Spinal Cord

The birth defect spina bifida is a failure of the vertebral arch to close, exposing the spinal cord. The spinal cord is a long, thin, tubular bundle of nervous tissue and

Structural Insights into the Chaperone-Assisted

In this study, we report the cryo-EM structure of the simplified tail fiber complexed with its chaperone from the myocyanophage Pam3, which provides insights into

ACL anatomy: Is there still something to learn?

They include the structure, shape and location of femoral and tibial insertion sites, the number of bundles and mid-substance characteristics, blood supply and innervation among the

Structural Insights into the Chaperone-Assisted Assembly of a

Abstract: At the first step of phage infection, the receptor-binding proteins (RBPs) such as tail fibers are responsible for recognizing specific host surface receptors. The proper folding and...

The structure of Shigella virus Sf14 reveals the

Other structures resolved here indicate that Sf14 particles have two sets of whiskers, two types of tail fibers, a Mu-like baseplate, and a central tail

Beam -shaped tail fiber failure

The bundle tail fiber is a crucial component in the fiber optic cable assembly, and any failure in this component can significantly impact the performance of the entire system. This article

Structure and function of ribbon synapses

The rod terminal often contains a single, large, crescent-shaped ribbon, but commonly it ''cracks'' into two separate ribbons (arrowheads) that maintain the overall crescent and serve a single invagination

Structural analysis enabled us to propose the assembly mechanism of phage tail fibers, in which the chaperone first protects the intertwined and repetitive distal moiety of each fiber subunit,

Spinal Cord

The spinal cord consists of bundles of nerve axons forming pathways that carry incoming and outgoing messages between the brain and the rest of the body.
