Surface electrostatic maps of adenylate kinase (Adk), β-galactosidase (β-Gal), DNA ligase (LigA), glycerol kinase (GlpK), histidinol-phosphate aminotransferase (HisC), malate dehydrogenase (MDH) and signal recognition particle 54 (SRP54) are shown for Escherichia coli (mesophile), Psychromonas ingrahamii (psychrophile), Haloferax volcanii (halophile), and Halorubrum lacusprofundi (psychrohalophile). Electrostatic potentials were calculated from predicted structures and mapped onto the molecular surface. Blue indicates positive electrostatic potential and red indicates negative electrostatic potential. -- Frontiers in Microbiology

Coordinated Proteome-scale Remodeling Underlies Polyextremophilic Survival In Antarctic Cryo-hypersaline Brines

by Keith CowingJune 24, 2026June 24, 2026

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 […]

New Analytical Methodology to Reveal Biosignatures on Mars and Ocean Worlds

by Keith CowingOctober 29, 2025October 29, 2025

Terrestrial analog environments and their microbial communities are key elements to prepare for the exploration of extraterrestrial planetary environments that potentially sustained, or even may still sustain, the (bio)chemistry necessary […]
