CC -!- FUNCTION: Mediates cleavage of dimethylsulfonioproprionate (DMSP) into
CC dimethyl sulfide (DMS) and acrylate. DMS is the principal form by which
CC sulfur is transported from oceans to the atmosphere and is a key
CC component of the ocean sulfur cycle. {ECO:0000250|UniProtKB:P0DN23}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=S,S-dimethyl-beta-propiothetin = acrylate + dimethyl sulfide +
CC H(+); Xref=Rhea:RHEA:19965, ChEBI:CHEBI:15378, ChEBI:CHEBI:16457,
CC ChEBI:CHEBI:17437, ChEBI:CHEBI:37080; EC=4.4.1.3;
CC Evidence={ECO:0000250|UniProtKB:P0DN21};
CC -!- SUBUNIT: Homotetramer. {ECO:0000250|UniProtKB:P0DN21}.
CC -!- SIMILARITY: Belongs to the aspartate/glutamate racemases family. ALMA1
CC subfamily. {ECO:0000305}.
