Homeoviscous Adaptation of Membranes in Archaea.

摘要: Because membranes play a central role in regulating fluxes inward and outward from the cells, maintaining appropriate structure of membrane is crucial to maintain cellular integrity functions. Microbes often face contrasted fluctuating environmental conditions, which they need adapt or die. Membrane adaptation achieved by modification lipid composition, strategy termed homeoviscous adaptation. Homeoviscous archaea involves strategies similar that observed bacteria eucarya, such as regulation chain length saturation levels, well specific archaea, number cycles along isoprenoid chains ratio between mono bipolar lipids. Although not described yet hyperthermophilic bacteria, it possible these two also apply latter organisms.
