Many bacteria interact with target organisms using syringe-like structures called contractile injection systems (CISs). CISs structurally resemble headless bacteriophages and share evolutionarily related proteins such as the tail tube, sheath, and baseplate complex. In many cases, CISs mediate trans-king...
Structure of bacteriophage T4 gene product 11, the interface between the baseplate and short tail fibers Bacteriophage T4, like all other viruses, is required to be stable while being transmitted from host to host, but also is poised to eject efficiently and r... Petr,G,Leiman,... - 《Jo...
Electron microscopy uncovered an unusualAckermannviridaetail structure that differs from the long, spindly tail fibers of the T4-like myovirus. Instead,Ackermannviridaefamily members have an elaborate organization of branched projections coupled with bulbous prongs protruding from the base plate. These bran...
The two structures that bacteria can utilize for movement are the flagella and cilium. Flagella are longer with like appendages, while the psyllium are shorter finger-like projections.Answer and Explanation: Become a member and unlock all Study Answers Start today. Try ...
Tail fibers generally have a fiber-like structure dominated by a long α-helix bundle with a C-terminal RBD, whereas tailspikes have an enzymatically active, β-helical, elongated struc- ture with no, one or two C-terminal carbohydrate- binding or chaperone domains [12]. Both terms are ...
Talin and kindlin are FERM (protein 4.1, ezrin, radixin, moesin) domain proteins consisting of F1, F2 and F3 subdomains and an additional N-terminal talin- and kindlin-specific ubiquitin-like F0 subdomain4,5. The F2 subdomain of kindlin harbors a pleckstrin homology (PH) domain, which bind...
Biochemistry and Cell BiologyF-type phage tail-like bacteriocins (PTLBs) are high-molecular-weight protein complexes exhibiting bactericidal activity and share evolutionary similarities with the tails of non-contractile siphoviruses. In this study, we present the atomic structure of monocin, a ...
There is a small upper canine, so the dental formula is the same as that of the Potoroidae, The upper first incisor is much larger than the other incisors, which are peglike (Fig. 4.26A and B). The premolars are not conspicuously sectorial, but are tricuspid. The molars are quadrilate...
Following the N-terminus of Get5 is a ubiquitin-like (Ubl) domain that interacts with the N-terminus of Sgt2. Here, the crystal structure of the Sgt2 dimerization domain complexed with the Get5 Ubl domain (Sgt2NGet5Ubl) is reported. This complex reveals an intimate interaction between one...
The basic lamin protomer is a homotypic dimer formed by parallel, unstaggered association of the rod domain to form a twostranded coiled-coil a-helix. This subunit, which forms a rod-like structure with a length of ~50 nm, engages in both head-to-tail and lateral interactions to form ...
