摘要：
The mitochondrial complex I (NADH:ubiquinone oxidoreductase) isolated from potato (Solanum tuberosum) has been investigated for the presence of iron-sulfur clusters. EPR spectroscopic analysis detected signals arising from clusters N1, N2, N3 and N4. Quantitation of the content of iron and sulfur within the isolated complex I showed the preparation to contain 22.6 mol acid-labile sulfide and 30.4 mol iron/mol complex I. The iron-sulfur cluster composition of the plant complex I appears to be similar to the well-known composition found in Neurospora crassa.
