Title	Quantitative proteomics of cold adaptation of the Antarctic archaeon Halohasta litchfieldiae and Halorubrum lacusprofundi
Description	Halohasta litchfieldiae and Halorubrum lacusprofundi are important members of Deep Lake in Antarctica, representing ~44% (the most abundance) and ~10% (the 3rd most abundance) of the lake population. Deep Lake is in the Vestfold Hills, East Antarctica (68°33’36.8S, 78°11’48.7E) and is 36 m deep, monomictic, and perennially cold (down to -20C) (DeMaere et al., 2013; Williams et al., 2014; Tschitschko et al., 2015; Tschitschko et al., 2016). In this project, using quantitative proteomics (8-plex iTRAQ labeling), proteins, pathways and cellular processes important for cold adaptation were determined for both Hht. litchfieldiae and Hrr. lacusprofundi. The data provided a new level of understanding about molecular mechanisms and regulatory networks involved in adaptation of the Antarctic haloarchaea to cold environment. DeMaere, M. Z., Williams, T.
