Protein attributes

Sequence length189 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

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 = NAD+ + ubiquinol.

NADH + acceptor = NAD+ + reduced acceptor.

Subunit structure

Complex I is composed of about 40 different subunits.

Subcellular location

Mitochondrion inner membrane; Single-pass membrane protein Potential.

Post-translational modification

The N-terminus is blocked.

Sequence caution

The sequence EAA36254.2 differs from that shown. Reason: Erroneous gene model prediction.
