A DNase encoded by integrated element CJIE1 inhibits natural transformation of Campylobacter jejuni.
The species Campylobacter jejuni is considered naturally competent for DNA uptake and displays strong genetic diversity. Nevertheless, nonnaturally transformable strains and several relatively stable clonal lineages exist. In the present study, the molecular mechanism responsible for the nonnatural transformability of a subset of C. jejuni strains was investigated. Comparative genome hybridizat...
Mechanical metamaterials are engineered materials whose structures give them novel mechanical properties, including negative Poisson's ratios, negative compressibilities and phononic bandgaps. Of particular interest are systems near the point of mechanical instability, which recently have been shown to distribute force and motion in robust ways determined by a nontrivial topological state. Here...
Transformable Robot In article number 2200051, Hong Suk Kang, Dong-Gyun Kim, Jong-Chan Lee, and co-workers present photo-controllable liquid crystalline networks (pc-LCNs) comprising static dynamic covalent dual-cross-links. The tailored network architecture of pc-LCNs enable UV-controllable reversible assembly/disassembly shape reconfiguration capabilities, while maintaining visible light-resp...
Synthetic skills are the prerequisite and foundation for the modern chemical and pharmaceutical industry. The same is true for nanotechnology, whose development has been hindered by the sluggish advance of its synthetic toolbox, i.e., the emerging field of nanosynthesis. Unlike organic chemistry, where the variety of functional groups provides numerous handles for designing chemical selectivity...
Model-Driven Architecture (MDA) developed by the Object Management Group (OMG) proposes three (or at least two) transformable models for system specification. The first one is a Computation Independent Model or CIM. The CIM is a model that should eliminate the gap between business people and software developers. Two other models are a Platform Independent Model (PIM) and a Platform Specific Mod...
Transformable polyhedral surfaces with rigid facets, i.e., rigid origami, are useful for designing kinetic and deployable structures. In order to apply rigid origami to various architectural and other engineering design purposes, it is essential to consider the geometry of origami in kinetic motion and provide sufficiently generalized methods to produce controlled variations of shapes that suit...
A lytic factor, associated with the cell wall, was fortuitously discovered during the course of the investigations described in the previous paper (1). In the pneumococcal transformation system (2-5) as well as in the Bacillus subtilis transformation system (6), the highly transformable strains possessed active autolytic enzymes. Consequently, studies were undertaken to investigate the relation...
