ectoine biosynthesis~Biosynthesis of ectoine (1,4,5,6-tetrahydro-2-methyl-4-pyrimidine carboxylic acid), an excellent osmoprotectant. Since Galinski et al. (PMID:3838936) discovered ectoine as a compatible solute in Ectothiorhodospira halochloris, an extremely halophilic phototrophic eubacterium, it has been found to be distributed widely in nature, largely in moderately halophilic eubacteria. The biosynthetic pathway of ectoine from aspartic b-semialdehyde (ASA) was first elucidated in Halomonas elongata by purification and characterization of each enzyme involved. |
