Psychrophile adaptations
WebAug 1, 2010 · These physiological adaptations are seen at many levels. Against a background of detailed comparative protein structural analyses, the recent surge of psychrophile proteome, genome, metagenome and transcriptome sequence data has triggered a series of sophisticated analyses of changes in global protein composition. WebWhen cells of psychrophiles are exposed to temperatures above their maximal growth temperatures, the ability to take up oxygen decreases. These thermally induced damages …
