IntEnz Enzyme Nomenclature


Accepted name:
ectoine hydrolase
Other name:
doeA (gene name)
Systematic name:
ectoine aminohydrolase



The enzyme, found in some halophilic bacteria, is involved in the degradation of the compatible solute ectoine. The enzyme, which belongs to peptidase family M24, only acts in the direction of ectoine hydrolysis. It also produces smaller amounts of (2S)-4-acetamido-2-aminobutanoate, which is recycled back to ectoine by EC, ectoine synthase.
