What makes Extremophilic Marine Microbes Molecular Specialists? Exploring adaptations with a focus on DNA polymerases and their potential applications in Biotechnology.

The natural world is inhabited by a wide range of organisms with diverse characteristics, all of which develop adaptations that allow them to coexist sustainably in their environments. Some organisms even live in extreme conditions, and these are called extremophiles. Temperature plays an important role in regulating all biochemical processes, including DNA synthesis and enzymatic activities. Through an extensive literature review and sequence alignment analysis, this research investigates the adaptations of DNA polymerase I in psychrophilic and thermophilic organisms, focusing on differences in amino acid composition that contribute to enzyme flexibility or stability. This research provides a deeper understanding of the mechanisms behind the evolutionary adaptations of extremophiles and their potential biotechnology applications.
