Function

ECTD_SPHAL Involved in the biosynthesis of 5-hydroxyectoine, called compatible solute, which helps organisms to survive extreme osmotic stress by acting as a highly soluble organic osmolyte. Catalyzes the 2-oxoglutarate-dependent selective hydroxylation of L-ectoine to yield (4S,5S)-5-hydroxyectoine.^{[1] [2]}
