General annotation (Comments)

Function	Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) that is believed to belong to the minimal assembly required for catalysis. Complex I functions in the transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone By similarity.
Catalytic activity	NADH + ubiquinone = NAD+ + ubiquinol. NADH + acceptor = NAD+ + reduced acceptor.
Cofactor	Binds 1 4Fe-4S cluster Potential.
Subunit structure	Complex I is composed of 45 different subunits This is a component of the iron-sulfur (IP) fragment of the enzyme By similarity.
Subcellular location	Mitochondrion By similarity.
Sequence similarities	Belongs to the complex I 20 kDa subunit family.
