Protein attributes

Sequence length	463 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

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.
Subunit structure	Complex I is composed of 45 different subunits. Component of the iron-sulfur (IP) fragment of the enzyme By similarity.
Subcellular location	Mitochondrion inner membrane; Peripheral membrane protein; Matrix sideBy similarity.
Sequence similarities	Belongs to the complex I 49 kDa subunit family.
