Chain A (FUCA_ECOLI | P0AB87)

molecular function
	GO:0008738	L-fuculose-phosphate aldolase activity	Catalysis of the reaction: L-fuculose 1-phosphate = (S)-lactaldehyde + glycerone phosphate.
	GO:0016832	aldehyde-lyase activity	Catalysis of the cleavage of a C-C bond in a molecule containing a hydroxyl group and a carbonyl group to form two smaller molecules, each being an aldehyde or a ketone.
	GO:0016829	lyase activity	Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
	GO:0008270	zinc ion binding	Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
	GO:0019571	D-arabinose catabolic process	The chemical reactions and pathways resulting in the breakdown of D-arabinose, the D-enantiomer of arabino-pentose.
	GO:0042355	L-fucose catabolic process	The chemical reactions and pathways resulting in the breakdown of L-fucose (6-deoxy-Lgalactose).
	GO:0005975	carbohydrate metabolic process	The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule.
	GO:0019317	fucose catabolic process	The chemical reactions and pathways resulting in the breakdown of fucose (6-deoxygalactose).
	GO:0006004	fucose metabolic process	The chemical reactions and pathways involving fucose, or 6-deoxygalactose, which has two enantiomers, D-fucose and L-fucose.
cellular component
	GO:0005829	cytosol	The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
