Putting life on ice: bacteria that bind to frozen water

Maya Bar Dolev, Reut Bernheim, Shuaiqi Guo, Peter L Davies, Ido Braslavsky
Journal of the Royal Society, Interface
2016

Ice-binding proteins (IBPs) are typically small, soluble proteins produced by cold-adapted organisms to help them avoid ice damage by either resisting or tolerating freezing. By contrast, the IBP of… (More)

Role of Ca²⁺ in folding the tandem β-sandwich extender domains of a bacterial ice-binding adhesin.

Shuaiqi Guo, Christopher P. Garnham, Sarathy Karunan Partha, Robert L. Campbell, John S Allingham, Peter L Davies
The FEBS journal
2013

A Ca(2+) -dependent 1.5-MDa antifreeze protein present in an Antarctic Gram-negative bacterium, Marinomonas primoryensis (MpAFP), has recently been reassessed as an ice-binding adhesin. The… (More)

Re-Evaluation of a Bacterial Antifreeze Protein as an Adhesin with Ice-Binding Activity

Shuaiqi Guo, Christopher P. Garnham, John C Whitney, Laurie A. Graham, Peter L Davies
PloS one
2012

A novel role for antifreeze proteins (AFPs) may reside in an exceptionally large 1.5-MDa adhesin isolated from an Antarctic Gram-negative bacterium, Marinomonas primoryensis. MpAFP was purified from… (More)

Blocking rapid ice crystal growth through nonbasal plane adsorption of antifreeze proteins.

Luuk L C Olijve, Konrad Meister, +4 authors Ilja K Voets
Proceedings of the National Academy of Sciences…
2016

Antifreeze proteins (AFPs) are a unique class of proteins that bind to growing ice crystal surfaces and arrest further ice growth. AFPs have gained a large interest for their use in antifreeze… (More)

Ca2+-stabilized adhesin helps an Antarctic bacterium reach out and bind ice

Tyler D. R. Vance, Luuk L C Olijve, Robert L. Campbell, Ilja K Voets, Peter L Davies, Shuaiqi Guo
Bioscience reports
2014

The large size of a 1.5-MDa ice-binding adhesin [MpAFP (Marinomonas primoryensis antifreeze protein)] from an Antarctic Gram-negative bacterium, M. primoryensis, is mainly due to its highly… (More)

Modeling repetitive, non-globular proteins.

Koli Basu, Robert L. Campbell, Shuaiqi Guo, Tianjun Sun, Peter L Davies
Protein science : a publication of the Protein…
2016

While ab initio modeling of protein structures is not routine, certain types of proteins are more straightforward to model than others. Proteins with short repetitive sequences typically exhibit… (More)

Conserved structural features anchor biofilm-associated RTX-adhesins to the outer membrane of bacteria.

Shuaiqi Guo, David N. Langelaan, Sean W Phippen, Steven P. Smith, Ilja K Voets, Peter L Davies
The FEBS journal
2018

Repeats-in-toxin (RTX) adhesins are present in many Gram-negative bacteria to facilitate biofilm formation. Previously, we reported that the 1.5-MDa RTX adhesin (MpIBP) from the Antarctic bacterium,… (More)

A Downlink Dynamic Resource Allocation Scheme for Multi-cell OFDMA System

Yueyun Chen, Shuaiqi Guo
2009 International Conference on Wireless…
2009

A Downlink radio resource allocation scheme based on ICI coordination for multi-cell OFDMA system is proposed. By dynamically determining frequency reuse factor, data rate of the users who have bad… (More)

RTX Adhesins are Key Bacterial Surface Megaproteins in the Formation of Biofilms.

Shuaiqi Guo, Tyler D. R. Vance, Corey A Stevens, Ilja K Voets, Peter L Davies
2019

Gram-negative bacteria produce repeats-in-toxin adhesion proteins (RTX adhesins) to facilitate microbial adhesion. These large, multidomain proteins share a common architecture comprised of four… (More)

Structure of a 1.5-MDa adhesin that binds its Antarctic bacterium to diatoms and ice

Shuaiqi Guo, Corey A Stevens, +13 authors Peter L Davies
Science Advances
2017

Bacterial adhesins are modular cell-surface proteins that mediate adherence to other cells, surfaces, and ligands. The Antarctic bacterium Marinomonas primoryensis uses a 1.5-MDa adhesin comprising… (More)
