The structure and subunit composition of the particulate NADH-ubiquinone reductase of bovine heart mitochondria.
Preparations of NADH-ubiquinone reductase from bovine heart mitochondria (Complex I) were shown to contain at least 16 polypeptides by gel electrophoresis in the presence of sodium dodecyl sulphate. 2. High-molecular-weight soluble NADH dehydrogenase prepared from Triton X-100 extracts of submitochondrial particles [Baugh & King (1972) Biochem. Biophys. Res. Commun. 49, 1165-1173] was similar t...
متن کاملIsocitrate dehydrogenase from bovine heart: primary structure of subunit 3/4.
Bovine NAD(+)-dependent isocitrate dehydrogenase was shown previously to contain four subunits of approx. 40 kDa (subunits 1-4) possessing different peptide maps and electrophoretic properties [Rushbrook and Harvey (1978) Biochemistry 17, 5339-5346]. In this study the heterogeneity is confirmed using enzyme purified by updated methods and from single animals, ruling out allelic variability. Sub...
متن کاملGeneration of superoxide anion by the NADH dehydrogenase of bovine heart mitochondria.
Submitochondrial particles from bovine heart in which NADH dehydrogenase is reduced by either addition of NADH and rotenone or by reversed electron transfer generate 0.9 +/- 0.1 nmol of O2-/min per mg of protein at pH 7.4 and at 30 degrees C. When NADH is used as substrate, rotenone, antimycin and cyanide increase O2- production. In NADH- and antimycin-supplemented submitochondrial particles, r...
متن کاملSubunit structure of dihydrolipoyl transacetylase component of pyruvate dehydrogenase complex from bovine heart.
Limited tryptic digestion of dihydrolipoyl transacetylase, the core enzyme of the bovine heart pyruvate dehydrogenase complex, cleaves the transacetylase subunits (Mr =: 52,000) into two large fragments, designated the subunit-binding domain and the lipoyl domain. The subunit-binding domain has a compact structure with M, = 26,000 as determined by sedimentation equilibrium analysis, and it poss...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
