A conformational switch involved in maturation of Staphylococcus aureus bacteriophage 80α capsids.

• Michael S. Spilman, Altaira D. Dearborn, Jenny R. Chang, Priyadarshan K. Damle, Gail E Christie, Terje Dokland
• Journal of molecular biology
• 2011

Bacteriophages are involved in many aspects of the spread and establishment of virulence factors in Staphylococcus aureus, including the mobilization of genetic elements known as S. aureus… (More)

The Staphylococcus aureus pathogenicity island 1 protein gp6 functions as an internal scaffold during capsid size determination.

• Altaira D. Dearborn, Michael S. Spilman, +5 authors Terje Dokland
• Journal of molecular biology
• 2011

Staphylococcus aureus pathogenicity island 1 (SaPI1) is a mobile genetic element that carries genes for several superantigen toxins. SaPI1 is normally stably integrated into the host genome but can… (More)

The carboxy-terminal coiled-coil of the RNA polymerase beta'-subunit is the main binding site for Gre factors.

• Marina N. Vassylyeva, Vladimir Svetlov, Altaira D. Dearborn, Sergiy Klyuyev, Irina Artsimovitch, Dmitry G. Vassylyev
• EMBO reports
• 2007

Bacterial Gre transcript cleavage factors stimulate the intrinsic endonucleolytic activity of RNA polymerase (RNAP) to rescue stalled transcription complexes. They bind to RNAP and extend their… (More)

α-Synuclein Amyloid Fibrils with Two Entwined, Asymmetrically Associated Protofibrils.

• Altaira D. Dearborn, Joseph S. Wall, +5 authors Alasdair C. Steven
• The Journal of biological chemistry
• 2016

Parkinson disease and other progressive neurodegenerative conditions are characterized by the intracerebral presence of Lewy bodies, containing amyloid fibrils of α-synuclein. We used cryo-electron… (More)

The roles of SaPI1 proteins gp7 (CpmA) and gp6 (CpmB) in capsid size determination and helper phage interference.

• Priyadarshan K. Damle, Erin A Wall, +5 authors Gail E Christie
• Virology
• 2012

SaPIs are molecular pirates that exploit helper bacteriophages for their own high frequency mobilization. One striking feature of helper exploitation by SaPIs is redirection of the phage capsid… (More)

Mobilization of pathogenicity islands by Staphylococcus aureus strain Newman bacteriophages

• Altaira D. Dearborn, Terje Dokland
• Bacteriophage
• 2012

Staphylococcus aureus pathogenicity islands (SaPIs) are mobile genetic elements that encode virulence factors and depend on helper phages for their mobilization. Such mobilization is specific and… (More)

Structure and size determination of bacteriophage P2 and P4 procapsids: function of size responsiveness mutations.

• Altaira D. Dearborn, Pasi Laurinmaki, +4 authors Terje Dokland
• Journal of structural biology
• 2012

Bacteriophage P4 is dependent on structural proteins supplied by a helper phage, P2, to assemble infectious virions. Bacteriophage P2 normally forms an icosahedral capsid with T=7 symmetry from the… (More)

Assembly of bacteriophage 80α capsids in a Staphylococcus aureus expression system.

• Michael S. Spilman, Priyadarshan K. Damle, +5 authors Terje Dokland
• Virology
• 2012

80α is a temperate, double-stranded DNA bacteriophage of Staphylococcus aureus that can act as a "helper" for the mobilization of S. aureus pathogenicity islands (SaPIs), including SaPI1. When SaPI1… (More)

Competing scaffolding proteins determine capsid size during mobilization of Staphylococcus aureus pathogenicity islands

• Altaira D. Dearborn, Erin A Wall, +7 authors Terje Dokland
• eLife
• 2017

Staphylococcus aureus pathogenicity islands (SaPIs), such as SaPI1, exploit specific helper bacteriophages, like 80α, for their high frequency mobilization, a process termed 'molecular piracy'. SaPI1… (More)

Chimeric rabbit/human Fab antibodies against the hepatitis Be-antigen and their potential applications in assays, characterization, and therapy.

• Xiaolei Zhuang, Norman R. Watts, +7 authors Paul T Wingfield
• The Journal of biological chemistry
• 2017

Hepatitis B virus (HBV) infection afflicts millions worldwide, causing cirrhosis and liver cancer. HBV e-antigen (HBeAg), a clinical marker for disease severity, is a soluble variant of the viral… (More)
