摘要:Legionella pneumophila encodes an extracellular secreted phospholipase A named PlaA that is translocated by the type II secretion system. It plays an essential role in maintaining the integrity of Legionella ‐containing vacuoles in L. pneumophila pathogenesis. Here, it is sh...

摘要:Formulations are given for the intensities of transmitted and diffracted waves in the Laue case of a perfect crystal. This is applicable irrespective of the magnitudes of both the real and imaginary parts of the Fourier components of the crystal polarizability. The phase shi...

摘要:Bacterial cytokinesis is mediated by the Z‐ring, which is formed by the prokaryotic tubulin homolog FtsZ. Recent data indicate that the Z‐ring is composed of small patches of FtsZ protofilaments that travel around the bacterial cell by treadmilling. Treadmilling involves a s...

摘要:Calpain is a Ca2+‐activated, heterodimeric cysteine protease consisting of a large catalytic subunit and a small regulatory subunit. Dysregulation of this enzyme is involved in a range of pathological conditions such as cancer, Alzheimer's disease and rheumatoid arthritis, a...

摘要:Piecewise linear descriptions are presented of weavings of threads, loops and 2‐periodic nets. Crystallographic data are provided for regular structures, defined as those with one kind (symmetry‐related) of vertex (corner) and edge (stick). These include infinite families of...

摘要:FtsZ, a tubulin‐like GTPase, is essential for bacterial cell division. In the presence of GTP, FtsZ polymerizes into filamentous structures, which are key to generating force in cell division. However, the structural basis for the molecular mechanism underlying FtsZ function...

摘要:The acceptance–rejection technique has been widely used in several Monte Carlo simulation packages for Rayleigh scattering of photons. However, the models implemented in these packages might fail to reproduce the corresponding experimental and theoretical results. The discre...

摘要:Quasicrystals, which have long‐range orientational order without translational symmetry, are incompatible with the theory of conventional crystals, which are characterized by periodic lattices and uniformly repeated unit cells. Reported here is a novel quasicrystal‐related s...
