EC 5.1.99.8

Names

Accepted name:
7,8-dihydroneopterin epimerase
Systematic name:
7,8-dihydroneopterin 2'-epimerase

Reaction

Comments:

The enzyme, which has been characterized in bacteria and plants, also has the activity of EC 4.1.2.25, dihydroneopterin aldolase. The enzyme from the bacterium Mycobacterium tuberculosis has an additional oxygenase function (EC 1.13.11.81, 7,8-dihydroneopterin oxygenase) [4].
