Tagatose-bisphosphate aldolase

The enzyme tagatose-bisphosphate aldolase catalyzes the chemical reaction


 * D -tagatose 1,6-bisphosphate $$\rightleftharpoons$$ glycerone phosphate + D glyceraldehyde 3-phosphate

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 D-tagatose 1,6-bisphosphate D-glyceraldehyde-3-phosphate-lyase (glycerone-phosphate-forming). This enzyme is also called D-tagatose-1,6-bisphosphate triosephosphate lyase. This enzyme participates in galactose metabolism.

Structural studies
