CC -!- FUNCTION: Involved in the degradation of L-fucose and D-arabinose
CC (PubMed:13898172). Catalyzes the reversible cleavage of L-fuculose 1-
CC phosphate (Fuc1P) to yield dihydroxyacetone phosphate (DHAP) and L-
CC lactaldehyde (PubMed:13898172, Ref.8, Ref.9, PubMed:10821675,
CC PubMed:11054289). Also able to catalyze the reversible cleavage of D-
CC ribulose 1-phosphate, but FucA has a higher affinity for L-fuculose 1-
CC phosphate and L-lactaldehyde than for D-ribulose 1-phosphate and
CC glycolaldehyde, respectively (PubMed:4928018). FucA possesses a high
CC specificity for the dihydroxyacetone phosphate (DHAP), but accepts a
CC great variety of different aldehydes and has a strong preference for L-
CC configurated alpha-hydroxy aldehydes (PubMed:13898172, Ref.8,
CC PubMed:10821675). FucA generates a vicinal diol unit having the
CC absolute (3R,4R)-cis configuration (D-erythro) (Ref.8,
CC PubMed:10821675). {ECO:0000269|PubMed:10821675,

CC KM=1.5 mM for L-fuculose 1-phosphate (Fuc1P) {ECO:0000269|Ref.9};
CC KM=2.2 mM for L-fuculose 1-phosphate (Fuc1P)
CC {ECO:0000269|PubMed:10821675};
CC Note=kcat is 19.3 sec(-1) for L-fuculose 1-phosphate (Fuc1P) as
CC substrate. {ECO:0000269|PubMed:10821675};
CC pH dependence:
CC Optimum pH is 7.2. {ECO:0000269|PubMed:13898172};
CC -!- PATHWAY: Carbohydrate degradation; L-fucose degradation; L-lactaldehyde
CC and glycerone phosphate from L-fucose: step 3/3. {ECO:0000255|HAMAP-
CC Rule:MF_00987, ECO:0000269|PubMed:13898172}.

CC ECO:0000269|PubMed:8676381}.
CC -!- INDUCTION: By L-fucose. {ECO:0000269|PubMed:4928018}.
CC -!- MISCELLANEOUS: During catalysis the binding of dihydroxyacetone
CC phosphate (DHAP) frees Glu-73 residue from its interaction with zinc
CC ion (PubMed:10821675, PubMed:11054289). Then Glu-73 residue abstracts a
CC proton from the C3 atom of dihydroxyacetone phosphate (DHAP) (or from
CC the O4 atom of L-fuculose 1-phosphate (Fuc1P) in the backward
CC reaction), and moves to transfer its proton to the aldehyde oxygen atom
CC (or to the C3 atom of dihydroxyacetone phosphate (DHAP))
CC (PubMed:10821675, PubMed:11054289). {ECO:0000269|PubMed:10821675,
CC ECO:0000269|PubMed:11054289}.
CC -!- SIMILARITY: Belongs to the aldolase class II family. AraD/FucA
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_00987, ECO:0000305}.
