Rhodopsin from Haloquadratum walsbyi is a light-driven magnesium transporter [PDF]
Nature CommunicationsThe functionally unknown Middle rhodopsin (HwMR) is a microbial rhodopsin (mRho) identified in Haloquadratum walsbyi, an archaeon that thrives in a 2 M MgCl2 environment harmful to most other microorganisms.

Haloquadratum walsbyi : Limited Diversity in a Global Pond
PLoS ONE, 2011 BackgroundHaloquadratum walsbyi commonly dominates the microbial flora of hypersaline waters. Its cells are extremely fragile squares requiring >14%(w/v) salt for growth, properties that should limit its dispersal and promote geographical isolation and ...

Fluorescence microscopy visualization of halomucin, a secreted 927 kDa protein surrounding Haloquadratum walsbyi cells [PDF]
Frontiers in Microbiology, 2015 At the time of its first publication, halomucin from Haloquadratum walsbyi strain HBSQ001 was the largest archaeal protein known (9159 aa). It has a predicted signal sequence, making it likely to be an extracellular or secreted protein.
