- Acetoin-ribose-5-phosphate transaldolase
enzymology, an acetoin-ribose-5-phosphate transaldolase (EC number|220.127.116.11) is an enzymethat catalyzes the chemical reaction
:3-hydroxybutan-2-one + D-ribose 5-phosphate acetaldehyde + 1-deoxy-D-altro-heptulose 7-phosphate
Thus, the two substrates of this enzyme are
3-hydroxybutan-2-oneand D-ribose 5-phosphate, whereas its two products are acetaldehydeand 1-deoxy-D-altro-heptulose 7-phosphate.
This enzyme belongs to the family of
transferases, specifically those transferring aldehydeor ketonic groups (transaldolases and transketolases, respectively). The systematic name of this enzyme class is 3-hydroxybutan-2-one:D-ribose-5-phosphate aldehydetransferase. Other names in common use include 1-deoxy-D-altro-heptulose-7-phosphate synthetase, 1-deoxy-D-altro-heptulose-7-phosphate synthase, 3-hydroxybutan-2-one:D-ribose-5-phosphate aldehydetransferase [wrong, and substrate name] . It employs one cofactor, thiamin diphosphate.
CAS registry numberfor this enzyme class is CAS registry|87843-76-3."
