 Title    Die Kristallstruktur des Ectoin, einer neuen osmoregulatorisch wirksamen Aminosäure The Crystal Structure of Ectoine, a Novel Amino Acid of Potential Osmoregulatory Function  
 Abstract    The crystal structure of ectoine (l,4,5,6-tetrahydro-2-methyl-4-pyrimidine carboxylic acid) iso­ lated from the extremely halophilic phototrophic bacterium Ectothiorhodospira halochloris was determined by X-ray analysis. This novel cyclic amino acid forms zwitterionic molecules with delocalized ^-bonding in the N-C-N group of the hydrated pyrimidine ring. The molecules are connected by N -H ...O hydrogen bonds. The excellent solubility of ectoine in water can be explained by its structural features which also account for its function as a compatible solute in halophilic bacteria.
