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. HAMAP-Rule MF_01357

Catalytic activity

NADH + ubiquinone + 5 H+(In) = NAD+ + ubiquinol + 4 H+(Out). HAMAP-Rule MF_01357

NADH + acceptor = NAD+ + reduced acceptor. HAMAP-Rule MF_01357

Subunit structure

Complex I is composed of about 30 different subunits.

Subcellular location

Mitochondrion inner membrane By similarity HAMAP-Rule MF_01357.

Sequence similarities

Belongs to the complex I 30 kDa subunit family.
