| Abstract: | 5-hydroxyeetoine is an effective compatible solute, it not only confers protection against osmotic stress, salt stress, temperature stress and dehydration, but also it has been considered for development in the pharmaceutical, bio-manufacturing and chemical industries. The eetoine hydroxylase, responsible for the conversion of ectoine to hydroxyectoine, is a member of the non-heme iron（ Ⅱ ）-containing and 2-oxoglutarate-dependent dioxygenases superfamily（EC 1.14.11）. Here, recent research on this enzyme was summarized, including its gene sources, activity detection, enzyme structure, catalytic mechanism and active centre. |
