CC   -!- FUNCTION: Catalyzes the isomerization of D-erythrulose-4P to D-
CC       erythrose-4P. Involved in the degradation pathways of L-threitol, D-
CC       threitol and erythritol, that allow M.smegmatis to grow on these
CC       compounds as the sole carbon source. {ECO:0000269|PubMed:26560079}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-erythrulose 4-phosphate = D-erythrose 4-phosphate;
CC         Xref=Rhea:RHEA:48784, ChEBI:CHEBI:16897, ChEBI:CHEBI:90796;
CC         EC=5.3.1.34; Evidence={ECO:0000269|PubMed:26560079};
CC   -!- PATHWAY: Carbohydrate metabolism; erythritol degradation.
CC       {ECO:0000269|PubMed:26560079}.
CC   -!- PATHWAY: Carbohydrate metabolism; D-threitol degradation.
CC       {ECO:0000269|PubMed:26560079}.
CC   -!- PATHWAY: Carbohydrate metabolism; L-threitol degradation.
CC       {ECO:0000269|PubMed:26560079}.
CC   -!- DISRUPTION PHENOTYPE: Cells lacking this gene are totally unable to
CC       grow on L-threitol. Cells lacking both derI1 and derI2 are totally
CC       unable to grow on D-threitol or on erythritol.
CC       {ECO:0000269|PubMed:26560079}.
CC   -!- SIMILARITY: Belongs to the LacAB/RpiB family. {ECO:0000305}.
