Coordinated Proteome-scale Remodeling Underlies Polyextremophilic Survival In Antarctic Cryo-hypersaline Brines
Introduction – Cryo-hypersaline brines combine sub-zero temperatures with near-saturated salinity, creating one of Earth’s most extreme habitats. Antarctic Deep Lake provides a natural model for studying how proteins remain stable […]
