CC   -!- FUNCTION: Catalyzes the isomerization of D-erythrulose-4P to L-
CC       erythrulose-1P. Involved in the degradation pathway of erythritol, that
CC       allows B.abortus to grow on this compound as the sole carbon source.
CC       {ECO:0000269|PubMed:25453104}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-erythrulose 1-phosphate = D-erythrulose 4-phosphate;
CC         Xref=Rhea:RHEA:49588, ChEBI:CHEBI:58002, ChEBI:CHEBI:90796;
CC         EC=5.3.1.33; Evidence={ECO:0000269|PubMed:25453104};
CC   -!- PATHWAY: Carbohydrate metabolism; erythritol degradation.
CC       {ECO:0000269|PubMed:25453104}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P9WG43}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P9WG43}.
CC   -!- DISRUPTION PHENOTYPE: Cells lacking this gene do not grow on erythritol
CC       as sole carbon source, in contrast to wild-type.
CC       {ECO:0000269|PubMed:25453104}.
CC   -!- SIMILARITY: Belongs to the triosephosphate isomerase family.
CC       {ECO:0000305}.
