Cottingham IR, Moore AL: Analysis of NADH dehydrogenases from plant [mung bean (Phaseolus aureus)] mitochondrial membranes on non-denaturing polyacrylamide gels and purification of complex I by band excision. Biochem J. 1988 Aug 15;254(1):303-5.
The present paper describes the analysis of plant mitochondrial NADH dehydrogenases using a recently developed non-dissociating gradient polyacrylamide-gel-electrophoresis technique [Kuonen, Roberts & Cottingham (1986) Anal. Biochem. 153, 221-226]. Solubilized mung-bean (Phaseolus aureus) submitochondrial particles were analysed on 3-22% (w/v) gradient polyacrylamide gels containing 0.1% Triton X-100 and stained for multiple NADH dehydrogenase activities. A rotenone-sensitive NADH dehydrogenase (Complex I) was identified on the basis of co-migration with the purified mammalian enzyme. The polypeptide composition of the plant enzyme was further analysed by band excision and SDS/polyacrylamide-gel electrophoresis. |
