CC   -!- FUNCTION: Involved in the biosynthesis of the coenzyme F420 which
CC       requires phospholactate produced via the aldol cleavage of L-fuculose
CC       1-phosphate and the NAD(+)-dependent oxidation of (S)-lactaldehyde.
CC       Catalyzes the reversible cleavage of L-fuculose 1-phosphate (Fuc1P) to
CC       yield dihydroxyacetone phosphate (DHAP) and S-lactaldehyde.
CC       {ECO:0000250|UniProtKB:Q58813}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-fuculose 1-phosphate = (S)-lactaldehyde + dihydroxyacetone
CC         phosphate; Xref=Rhea:RHEA:12933, ChEBI:CHEBI:18041,
CC         ChEBI:CHEBI:57642, ChEBI:CHEBI:57846; EC=4.1.2.17;
CC         Evidence={ECO:0000250|UniProtKB:Q58813};
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000250|UniProtKB:Q58813};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000250|UniProtKB:P0AB87};
CC   -!- PATHWAY: Cofactor biosynthesis; coenzyme F420 biosynthesis.
CC       {ECO:0000250|UniProtKB:Q58813}.
CC   -!- SUBUNIT: Homotetramer. {ECO:0000250|UniProtKB:Q58813}.
CC   -!- SIMILARITY: Belongs to the aldolase class II family. AraD/FucA
CC       subfamily. {ECO:0000250|UniProtKB:Q58813}.
