FunFam 39867: Electron transport complex subunit B

There are 5 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
Dihydropyrimidine dehydrogenase (NADP(+)). [EC: 1.3.1.2]
5,6-dihydrouracil + NADP(+) = uracil + NADPH.
  • Also acts on dihydrothymine.
 4 A0A1E9VTG4 A0A1J0NQ83 D5VBT9 I2B007
Transferred entry: 1.6.5.11. [EC: 1.6.99.5]
    		3 B2A3S2 E1JS01 G7Q9G5
    Hydrogen dehydrogenase. [EC: 1.12.1.2]
    H(2) + NAD(+) = H(+) + NADH.
      		 1 A0A0D0SD71
      CoB--CoM heterodisulfide reductase. [EC: 1.8.98.1]
      Coenzyme B + coenzyme M + methanophenazine = N-(7-((2-sulfoethyl)dithio)heptanoyl)-O(3)-phospho-L-threonine + dihydromethanophenazine.
      • Found in methanogenic archaea, particularly Methanosarcina species, and regenerates coenzyme M and coenzyme B after the action of EC 2.8.4.1.
      • Highly specific for both coenzyme M and coenzyme B.
      • Reacts with various phenazine derivatives, including 2-hydroxyphenazine and 2-bromophenazine.
      • Formerly EC 1.12.99.2.
      		 1 U2ENS0
      Hydrogen dehydrogenase (NADP(+)). [EC: 1.12.1.3]
      H(2) + NADP(+) = H(+) + NADPH.
      • The protein from the bacterium Desulfovibrio fructosovorans exclusively functions as a hydrogen dehydrogenase, while the enzyme from the archaeon Pyrococcus furiosus is part of a heterotetrameric complex where the alpha and delta subunits function as a hydrogenase while the beta and gamma subunits function as sulfur reductase (EC 1.12.98.4).
      • Different from EC 1.12.1.5.
