CATH Superfamily 1.20.1440.230
NADH-ubiquinone oxidoreductase 51kDa subunit, iron-sulphur binding domain
The name of this superfamily has been modified since the most recent official CATH+ release (v4_4_0). At the point of the last release, this superfamily was named:
"NADH-ubiquinone oxidoreductase 51kDa subunit, iron-sulphur binding domain
".
FunFam 2: NADH-quinone oxidoreductase subunit F
Please note: GO 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.
There are 7 GO terms relating to "molecular function"

Plasma membrane respiratory chain complex I GO:0045272
A subcomplex of the respiratory chain located in the plasma membrane. It contains about 25 different polypeptide subunits, including NADH dehydrogenase (ubiquinone), flavin mononucleotide and several different iron-sulfur clusters containing non-heme iron. The iron undergoes oxidation-reduction between Fe(II) and Fe(III), and catalyzes proton translocation linked to the oxidation of NADH by ubiquinone. Examples of this component are found in bacterial species.
