General Information
Term respiratory chain complex I ID (Ontology) GO:0045271 (Gene Ontology)
Definition Respiratory chain complex I is an enzyme of the respiratory chain. It consists of several polypeptide chains and is L-shaped, with a horizontal arm lying in the membrane and a vertical arm that projects into the matrix. The electrons of NADH enter the chain at this complex.[ ISBN:0716749556 ]
Also Known As "NADH dehydrogenase (ubiquinone) complex" ; "NADH dehydrogenase complex (ubiquinone)" ; "NADH-Q oxidoreductase complex"
