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:P0DN21}.
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}.
