Hydroxylamine oxidoreductase (HAO) catalyzes the oxidation of hydroxylamine to nitrite in Nitrosomonas europaea. The electrons released in the reaction are partitioned to ammonium monooxygenase and to the respiratory chain. The immediate acceptor of electrons from HAO is believed to be cytochrome c-554 (Cyt c-554). We have isolated a genomic DNA fragment containing the structural gene encoding ...
Bu çalışmada, Şanlıurfa yöresindeki Akkaraman (AK) ve İvesi (IV) koyunlarının filogenetik yapıları moleküler tekniklerle belirlenmeye çalışılmıştır. Araştırmanın hayvan materyalini, yöresinde yetiştirilen koyunları oluşturmuştur. Koyunlardan genomik DNA izolasyonu için kıl örnekleri toplanmış tüm örneklerden izole edilmiştir. Koyun örneklerinde mitokondriyal Sitokrom b (Cyt b) gen bölgelerini ç...
Tetraheme cytochrome c 3 (cyt c 3) exhibits extremely low reduction potentials and unique properties. Since axial ligands should be the most important factors for this protein, every axial histidine of Desulfovibrio vulgaris Miyazaki F cyt c 3 was replaced with methionine, one by one. On mutation at the fifth ligand, the relevant heme could not be linked to the polypeptide, revealing the essent...
Knowledge on domain swapping in vitro is increasing, but domain swapping may not occur regularly in vivo, and its information in cells is limited. Herein, we show that domain-swapped oligomers of a thermostable c-type cytochrome, Hydrogenobacter thermophilus cyt c552, are formed in E. coli which expresses cyt c552. The region containing the N-terminal α-helix and heme was domain-swapped between...
Chilling injury is sustained by dry pollen of Typha latifolia L. upon hydration in germination medium at 0 degrees C. This injury is evidenced as poor germination, low vigor, and depressed respiration. Isolated mitochondria showed multiple sites of impaired electron transport. Besides losses of cytochrome (Cyt) c and NAD(+), the activities of membrane-bound enzyme complexes such as Cyt oxidase,...
• The water-soluble cyt. c is a mobile carrier within the respiratory chain electron transfer by facilitated supercomplex formation distance and close binding of in respirasome reflect diffusion channelling behaviour
Many anticancer drugs activate caspases via the mitochondrial apoptosis pathway. Activation of this pathway triggers a concomitant bioenergetic crisis caused by the release of cytochrome-c (cyt-c). Cancer cells are able to evade these processes by altering metabolic and caspase activation pathways. In this study, we provide the first integrated system study of mitochondrial bioenergetics and ap...
Time-resolved surface enhanced infrared absorption (SEIRA) spectroscopy is employed to analyse the dynamics of the protein structural changes coupled to the electron transfer process of immobilised cytochrome c (Cyt-c). Upon electrostatic binding of Cyt-c to Au electrodes coated with self-assembled monolayers (SAMs) of carboxyl-terminated thiols, cyclic voltammetric measurements demonstrate a r...
We present a novel platform for investigating the composition-specific interactions of proteins (or other biologically relevant molecules) with model membranes composed of compositionally distinct domains. We focus on the interaction between a mitochondrial-specific lipid, cardiolipin (CL), and a peripheral membrane protein, cytochrome c (cyt c). We engineer vesicles with compositions such that...
Demolybdo nitrate reductase (also called cyt c reductase) of Chlorella vulgaris has been converted to active nitrate reductase by insertion of Mo from Na2MoO4 in vitro. A procedure is described which consistently gives about 0.3 unit of nitrate reductase from about 6 units of cyt c reductase, a yield of 30% of the maximum expected, if we calculate on a basis of a ratio of 6 to 1 for the cyt c r...
