[[http://www.uniprot.org/uniprot/ECTD_VIRSA ECTD_VIRSA]] Involved in the biosynthesis of ectoine ((S)-2-methyl-1,4,5,6-tetrahydropyrimidine-4-carboxylic acid) which is a highly soluble organic osmolyte, called compatible solute, use to avoid excessive water efflux, plasmolysis, molecular crowding of the cytoplasm, and cessation of growth in high salinity environments. Catalyzes the 2-oxoglutarate-dependent selective hydroxylation of L-ectoine to yield (4S,5S)-5-hydroxyectoine.<ref>PMID:17636255</ref>
