Lesson plan
Ectoine
Ectoine (3,4,5,6-tetrahydro-2-methyl-4-pyrimidinecarboxylic acid) is a natural compound found in several species of bacteria. It is a compatible solute which serves as a protective substance by acting as an osmolyte and thus helps organisms survive extreme osmotic stress. Furthermore it was shown to protect DNA against ionizing and ultraviolet radiation serving as a radical scavenger. Ectoine is found in high concentrations in halophilic microorganisms and confers resistance towards salt and temperature stress. Ectoine was first identified in the microorganism Ectothiorhodospira halochloris, but has since been found in a wide range of Gram-negative and Gram-positive bacteria. Other species of bacteria in which ectoine was found include: * Brevibacterium linens * Halomonas elongata * Marinococcus halophilus * Pseudomonas stutzeri * Halomonas titanicae * Halorhodospira halophila * Halomonas ventosae
