Mechanism of Tc toxin action revealed in molecular detail.

Dominic Meusch et al.

Nature, 508(7494), 61-65 (2014-02-28)

Tripartite Tc toxin complexes of bacterial pathogens perforate the host membrane and translocate toxic enzymes into the host cell, including in humans. The underlying mechanism is complex but poorly understood. Here we report the first, to our knowledge, high-resolution structures

Polar residues and their positional context dictate the transmembrane domain interactions of influenza A neuraminidases.

Johan Nordholm et al.

The Journal of biological chemistry, 288(15), 10652-10660 (2013-03-01)

Interactions that facilitate transmembrane domain (TMD) dimerization have been identified mainly using synthetic TMDs. Here, we investigated how inherent properties within natural TMDs modulate their interaction strength by exploiting the sequence variation in the nine neuraminidase subtypes (N1-N9) and the

Identification and characterization of sialidase-like activity in the developmental stages of Amblyomma variegatum.

Audu J Natala et al.

Journal of medical entomology, 50(1), 85-93 (2013-02-23)

Amblyomma variegatum F. are obligate hematophagous ectoparasites of livestock that serve as the vectors of Ehrlichia ruminantium (formerly known as Cowdria ruminantium), the causative agent of heartwater disease. In the light of the fact that they are blood-feeding, their salivary

The M segment of the 2009 pandemic influenza virus confers increased neuraminidase activity, filamentous morphology, and efficient contact transmissibility to A/Puerto Rico/8/1934-based reassortant viruses.

Patricia J Campbell et al.

Journal of virology, 88(7), 3802-3814 (2014-01-17)

The 2009 H1N1 lineage represented the first detection of a novel, highly transmissible influenza A virus genotype: six gene segments originated from the North American triple-reassortant swine lineage, and two segments, NA and M, derived from the Eurasian avian-like swine

Antigenic and receptor binding properties of enterovirus 68.

Tadatsugu Imamura et al.

Journal of virology, 88(5), 2374-2384 (2013-12-29)

Increased detection of enterovirus 68 (EV68) among patients with acute respiratory infections has been reported from different parts of the world in the late 2000s since its first detection in pediatric patients with lower-respiratory-tract infections in 1962. However, the underlying
