Electron Transport Complex I MeSH Descriptor Data 2025
A flavoprotein and iron sulfur-containing oxidoreductase complex that catalyzes the conversion of UBIQUINONE to ubiquinol. In MITOCHONDRIA the complex also couples its reaction to the transport of PROTONS across the internal mitochondrial membrane. The NADH DEHYDROGENASE component of the complex can be isolated and is listed as EC 1.6.99.3.
2004; NADH DEHYDROGENASE (UBIQUINONE) was indexed under NADH, NADPH OXIDOREDUCTASES 1992-2003; for NADH DEHYDROGENASE use NADH DEHYDROGENASE 1990-2003; for UBIQUINONE REDUCTASE see NAD(P)H DEHYDROGENASE (QUINONE) 1992-1999
History Note
2004; for NADH DEHYDROGENASE (UBIQUINONE) use ELECTRON TRANSPORT COMPLEX I (NM) 1992-2003; for NADH DEHYDROGENASE COMPLEX 1 use NADH DEHYDROGENASE 1989-2003; for UBIQUINONE REDUCTASE use NAD(P)H DEHYDROGENASE (QUINONE) 1992-1999
