The enzyme rhamnulose-1-phosphate aldolase (EC 4.1.2.19) catalyzes the chemical reaction
- L-rhamnulose 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-rhamnulose-1-phosphate (S)-lactaldehyde-lyase (glycerone-phosphate-forming). Other names in common use include rhamnulose phosphate aldolase, L-rhamnulose 1-phosphate aldolase, L-rhamnulose-phosphate aldolase, and L-rhamnulose-1-phosphate lactaldehyde-lyase. This enzyme participates in pentose and glucuronate interconversions and fructose and mannose metabolism.
Structural studies[edit]
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 1GT7 and 1OJR.
