Enzyme Information

1.1.1.305
UDP-glucuronic acid oxidase (UDP-4-keto-hexauronic acid decarboxylating).
based on mapping to UniProt P77398
UDP-alpha-D-glucuronate + NAD(+) = UDP-beta-L-threo-pentapyranos-4-ulose + CO(2) + NADH.
-!- The activity is part of a bifunctional enzyme also performing the reaction of EC 2.1.2.13. -!- Formerly EC 1.1.1.n1.
2.1.2.13
UDP-4-amino-4-deoxy-L-arabinose formyltransferase.
based on mapping to UniProt P77398
10-formyltetrahydrofolate + UDP-4-amino-4-deoxy-beta-L-arabinose = 5,6,7,8-tetrahydrofolate + UDP-4-deoxy-4-formamido-beta-L-arabinose.
-!- The activity is part of a bifunctional enzyme also performing the reaction of EC 1.1.1.305. -!- Formerly EC 2.1.2.n1.
