Enzyme Information
| 4.1.2.13 |
Fructose-bisphosphate aldolase.
based on mapping to UniProt P0AB71
D-fructose 1,6-bisphosphate = glycerone phosphate + D-glyceraldehyde 3-phosphate.
-!- Also acts on (3S,4R)-ketose 1-phosphates. -!- The enzymes increase electron-attraction by the carbonyl group, some (Class I) forming a protonated imine with it, others (Class II), mainly of microbial origin, polarizing it with a metal ion, e.g. zinc. -!- Formerly EC 4.1.2.7.
