General description

Ectoine, also known as 4,5,6-tetrahydro-2-methyl-4-pyrimidinecarboxylic acid, is a zwitterionic amino acid derivative that is a compatible osmoprotectant solute produced in certain aerobic, chemoheterotrophic, and halophilic bacteria to protect against osmotic stress, radiation, and other unfavorable environmental conditions.

Application

The practical applications of ectoine include enzyme stabilization, anti-inflammatory treatment, neurodegenerative disease prevention, and other therapeutic applications.

Biochem/physiol Actions

Ectoine works as an enzyme stabilizer by maintaining hydration and reducing enzyme denaturation due to temperature changes. It also increases the stability of double-stranded DNA at high temperatures.

We have performed Molecular Dynamics simulations of ectoine, hydroxyectoine and urea in explicit solvent. Special attention has been spent on the local surrounding structure of water molecules. Our results indicate that ectoine and hydroxyectoine are able to accumulate more water

The protective properties of ectoine, formerly described for only extremophilic microorganisms, can be transferred to human skin. Our present data show that the compatible solute ectoine protects the cellular membrane from damage caused by surfactants. Transepidermal water loss measurements in

Cellular response during the freeze-thaw process strongly affects the cryopreservation outcome including cell morphology and cell viability. Cryomicroscopy was used to individually analyze the osmotic response of human pulmonary microvascular endothelial cells (HPMECs) during slow cooling (1 °C/min) to -60

Mycobacterium smegmatis is a commonly used mycobacterial model system. Here, we show that M. smegmatis protects itself against elevated salinity by synthesizing ectoine and hydroxyectoine and characterize the phenotype of a nonproducing mutant. This is the first analysis of M.
