The enzyme L-fuculose-phosphate aldolase (EC 4.1.2.17) catalyzes the chemical reaction

L-fuculose-1-phosphate glycerone phosphate^[1] + (S)-lactaldehyde

This enzyme belongs to the family of lyases, specifically the aldehyde-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is L-fuculose-1-phosphate (S)-lactaldehyde-lyase (glycerone-phosphate-forming). Other names in common use include L-fuculose 1-phosphate aldolase, fuculose aldolase, and L-fuculose-1-phosphate lactaldehyde-lyase. This enzyme participates in fructose and mannose metabolism.

As of late 2007, 20 structures have been solved for this class of enzymes, with PDB accession codes 1DZU, 1DZV, 1DZW, 1DZX, 1DZY, 1DZZ, 1E46, 1E47, 1E48, 1E49, 1E4A, 1E4B, 1E4C, 1FUA, 2FK5, 2FLF, 2FUA, 2OPI, 3FUA, and 4FUA.
