Bacteriophage T5, a Siphovirus belonging to the order Caudovirales, has a flexible, three-fold symmetric tail, to which three L-shaped fibres are attached. These fibres recognize...
This is a continuation from the previous tutorial - metal-coated fibers. 1. Transverse Modes in Optical Resonators Laser cavities differ in several significant ways from
Here, we introduce RBPseg, a method that combines monomeric ESMFold predictions with a structural-based domain identification approach, to divide tail fiber sequences into manageable
The T5 family of viruses are tailed bacteriophages characterized by a long non-contractile tail. The bacteriophage DT57C is closely related to the paradigmal T5 phage, though it recognizes a
In this work we discuss optical fiber designs that shape the output beam profile to more closely correspond to what is required in many real world industrial applications.
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.
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
The T5-like siphoviruses DT57C and DT571/2, isolated from horse feces, are very closely related to each other, and most of their structural proteins are also nearly identical to T5 phage. Their
To address this issue, we introduce the concept of the double-funnel-shaped beam (DFSB). For a funnel-shaped structure, the narrow part is referred to as the tail. Fig. 1 (a) shows the
Bacteriophage T5, a Siphovirus belonging to the order Caudovirales, has a flexible, three-fold symmetric tail, to which three L-shaped fibres are attached. These
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 the assembly mechanism of
Pigtail, also known as pigtail, has only one end with a connector, and the other end is a broken end of a fiber optic cable core. It is connected to other fiber optic cable cores by welding.
Here, we investigate the tail fibre and Tfa of Escherichia coli phage Mu. We demonstrate that Tfa forms a stable complex with the tail fibre, and present a 2.1 Å resolution X-ray crystal...
A new class of all-fiber beam shaping devices has been realized by inverse etching the end face of single mode and multimode fibers to form a
A tail fiber, also known as a fiber optic patch cord, consists of a connector on one end and a cut end of the fiber optic cable core on the other. These patch cords are primarily used to
Structure of the carboxy-terminal domain of the bacteriophage T5 L-shaped tail fibre. (A) Overall side stereo-view of pb1 (970–1263) in cartoon representation. Monomers are coloured
We demonstrate an adaptive wave-front shaping of optical beams transmitted through fiber bundles as a powerful resource for multisite, high
RBPseg enables accurate modeling of tail fiber structure, providing the first comprehensive tail fiber structure atlas.
