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.
  • CATALYTIC ACTIVITY: NADH + acceptor = NAD+ + reduced acceptor.
  • SUBUNIT: Complex I is composed of about 30 different subunits.
  • SUBCELLULAR LOCATION: Mitochondrion inner membrane; Peripheral membrane protein; Matrix side.
  • RNA EDITING: Modified_positions=31, 38, 100, 110, 123; Note=By similarity.
  • SIMILARITY: Belongs to the complex I 30 kDa subunit family.
