Enzyme Information
| 7.1.1.1 |
Proton-translocating NAD(P)(+) transhydrogenase.
based on mapping to UniProt P11024
NADPH + NAD(+) + H(+)(Side 1) = NADP(+) + H(+)(Side 2) + NADH.
-!- The enzyme is a membrane bound proton-translocating pyridine nucleotide transhydrogenase that couples the reversible reduction of NADP by NADH to an inward proton translocation across the membrane. -!- In the bacterium Escherichia coli the enzyme provides a major source of cytosolic NADPH. -!- Detoxification of reactive oxygen species in mitochondria by glutathione peroxidases depends on NADPH produced by this enzyme. -!- Formerly EC 1.6.1.5.
