A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.
ENZYME entry: EC 3.6.1.45
| Accepted Name |
|---|
| UDP-sugar diphosphatase.
|
| Alternative Name(s) |
|---|
| Nucleosidediphosphate-sugar diphosphatase. |
| Nucleosidediphosphate-sugar pyrophosphatase. |
| UDP-sugar hydrolase. |
| UDP-sugar pyrophosphatase. |
| Reaction catalysed |
|---|
| UDP-sugar + H(2)O <=> UMP + alpha-D-aldose 1-phosphate |
| Cofactor(s) |
|---|
| Divalent cation.
|
| Comment(s) |
|---|
- UDP-sugar is the best substrate, although other nucleoside-sugar
diphosphates are used as substrates with similar Km values but much
lower maximum velocities.
- Thus, this enzyme has a specificity distinct from that of
EC 3.6.1.21.
- Some but not all enzymes of this class also appear to have EC 3.1.3.5
activity.
