UnknownIdentification and characterization of pvuA, a gene encoding the ferric vibrioferrin receptor protein in Vibrio parahaemolyticus.
We previously reported that Vibrio parahaemolyticus expresses two outer membrane proteins of 78 and 83 kDa concomitant with production of siderophore vibrioferrin in response to iron starvation stress and that these proteins are the ferric vibrioferrin receptor and heme receptor, respectively (S. Ya...

UnknownDomain architecture of the stator complex of the A1A0-ATP synthase from Thermoplasma acidophilum.
A key structural element in the ion translocating F-, A-, and V-ATPases is the peripheral stalk, an assembly of two polypeptides that provides a structural link between the ATPase and ion channel domains. Previously, we have characterized the peripheral stalk forming subunits E and H of the A-ATPase...

UnknownAnticancer Activity of Reconstituted Ribonuclease S-Decorated Artificial Viral Capsid.
Ribonuclease S (RNase S) is an enzyme that exhibits anticancer activity by degrading RNAs within cancer cells; however, the cellular uptake efficiency is low due to its small molecular size. Here we generated RNase S-decorated artificial viral capsids with a size of 70-170 nm by self-assembly of the...

UnknownCapturing structural changes of the S<sub>1</sub> to S<sub>2</sub> transition of photosystem II using time-resolved serial femtosecond crystallography.
Photosystem II (PSII) catalyzes light-induced water oxidation through an S i -state cycle, leading to the generation of di-oxygen, protons and electrons. Pump-probe time-resolved serial femtosecond crystallography (TR-SFX) has been used to capture structural dynamics of light-sensi...

UnknownThe bovine leukemia virus-derived long non-coding RNA AS1-S binds to bovine hnRNPM and alters the interaction between hnRNPM and host mRNAs.
Viruses utilize several strategies to cause latent infection and evade host immune responses. Long non-coding RNA (lncRNA), a class of non-protein-encoding RNA that regulates various cellular functions by interacting with RNA-binding proteins, plays important roles for viral latency in several virus...

UnknownIdentification of transforming hepatitis B virus S gene nonsense mutations derived from freely replicative viruses in hepatocellular carcinoma.

Background & aims

The correlation between chronic hepatitis B virus (HBV) infection and hepatocellular carcinoma (HCC) has been well-established. But the roles of viral factor remain uncertain. Only HBV X gene and nonsense mutations of S gene (C-terminal truncation of HBV surface protein) ha...

UnknownMaximizing T c by tuning nematicity and magnetism in FeSe1-x S x superconductors.
A fundamental issue concerning iron-based superconductivity is the roles of electronic nematicity and magnetism in realising high transition temperature (T c). To address this issue, FeSe is a key material, as it exhibits a unique pressure phase diagram involving non-magnetic nematic and ...

UnknownPressure-induced reconstitution of Fermi surfaces and spin fluctuations in S-substituted FeSe.
FeSe is a unique high-[Formula: see text] iron-based superconductor in which nematicity, superconductivity, and magnetism are entangled with each other in the P-T phase diagram. We performed [Formula: see text]Se-nuclear magnetic resonance measurements under pressures of up to 3.9 GPa on 12% S-subst...

UnknownTwo superconducting states with broken time-reversal symmetry in FeSe1-xSx.
Iron-chalcogenide superconductors FeSe1-xSx possess unique electronic properties such as nonmagnetic nematic order and its quantum critical point. The nature of superconductivity with such nematicity is important for understanding the mechanism of unconventional s...

UnknownFundamental differences in endoreplication in mammals and Drosophila revealed by analysis of endocycling and endomitotic cells.
Throughout the plant and animal kingdoms specific cell types become polyploid, increasing their DNA content to attain a large cell size. In mammals, megakaryocytes (MKs) become polyploid before fragmenting into platelets. The mammalian trophoblast giant cells (TGCs) exploit their size to form a barr...
