FunFam 4540: Dihydroneopterin aldolase 2

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Dihydroneopterin aldolase. [EC: 4.1.2.25]
7,8-dihydroneopterin = 6-hydroxymethyl-7,8-dihydropterin + glycolaldehyde.
  • The enzyme participates in folate (in bacteria, plants and fungi) and methanopterin (in archaea) biosynthesis.
  • The enzymes from the bacterium Escherichia coli and the plant Arabidopsis thaliana also catalyze the epimerisation of the 2' hydroxy-group (EC 5.1.99.8).
  • The enzyme from the bacterium Mycobacterium tuberculosis is trifunctional and also catalyzes EC 5.1.99.8, and EC 1.13.11.81.
  • The enzyme from the yeast Saccharomyces cerevisiae also catalyzes the two subsequent steps in the folate biosynthesis pathway - EC 2.7.6.3, and EC 2.5.1.15.

7,8-dihydroneopterin epimerase. [EC: 5.1.99.8]
7,8-dihydroneopterin = 7,8-dihydromonapterin.
  • The enzyme, which has been characterized in bacteria and plants, also has the activity of EC 4.1.2.25.
  • The enzyme from the bacterium Mycobacterium tuberculosis has an additional oxygenase function (EC 1.13.11.81).
