General annotation (Comments)

Function

Transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone.

Catalytic activity

NADH + ubiquinone + 5 H+(In) = NAD+ + ubiquinol + 4 H+(Out).

NADH + acceptor = NAD+ + reduced acceptor.

Subunit structure

Complex I is composed of about 45 different subunits By similarity.

Subcellular location

Mitochondrion inner membrane; Peripheral membrane protein; Matrix side.
