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_01358

Catalytic activity

NADH + ubiquinone + 5 H+(In) = NAD+ + ubiquinol + 4 H+(Out). HAMAP-Rule MF_01358

NADH + acceptor = NAD+ + reduced acceptor. HAMAP-Rule MF_01358

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. Interacts with NDUFAF3 By similarity.

Subcellular location

Mitochondrion inner membrane; Peripheral membrane protein; Matrix side By similarity HAMAP-Rule MF_01358.

Sequence similarities

Belongs to the complex I 49 kDa subunit family.
