CC -!- FUNCTION: Catalyzes the circularization of gamma-N-acetyl-alpha,gamma-
CC diaminobutyric acid (ADABA) to ectoine (1,4,5,6-tetrahydro-2-methyl-4-
CC pyrimidine carboxylic acid), which is an excellent osmoprotectant.
CC {ECO:0000256|HAMAP-Rule:MF_01255}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2S)-4-acetamido-2-aminobutanoate = H2O + L-ectoine;
CC Xref=Rhea:RHEA:17281, ChEBI:CHEBI:15377, ChEBI:CHEBI:58515,
CC ChEBI:CHEBI:58929; EC=4.2.1.108;
CC Evidence={ECO:0000256|ARBA:ARBA00000511, ECO:0000256|HAMAP-
CC Rule:MF_01255};
CC -!- PATHWAY: Amine and polyamine biosynthesis; ectoine biosynthesis; L-
CC ectoine from L-aspartate 4-semialdehyde: step 3/3.
CC {ECO:0000256|ARBA:ARBA00005181, ECO:0000256|HAMAP-Rule:MF_01255}.
CC -!- SIMILARITY: Belongs to the ectoine synthase family.
CC {ECO:0000256|ARBA:ARBA00009637, ECO:0000256|HAMAP-Rule:MF_01255}.
