Enzyme Information
| 3.6.1.45 |
UDP-sugar diphosphatase.
based on mapping to UniProt P07024
UDP-sugar + H(2)O = UMP + alpha-D-aldose 1-phosphate.
-!- 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.
|
| 3.1.3.5 |
5'-nucleotidase.
based on mapping to UniProt P07024
A 5'-ribonucleotide + H(2)O = a ribonucleoside + phosphate.
-!- Wide specificity for 5'-nucleotides.
