در سال های اخیر پیشرفت های زیادی در شناسایی و تعیین توالی ژن ها و پروتئین ها صورت گرفته است که منجر به حجم زیادی از داده های بیولوژیکی در این زمینه شده است. برای بسیاری از توالی های شناخته شده به عنوان پروتئین، هنوز فانکشن مشخصی معرفی نشده است. روش های آزمایشگاهی تعیین فانکشن، بسیار هزینه بر و وقت گیر است. این موضوع یکی از مهم ترین چالش های بیولوژی مولکولی است. روش های فراوانی برای این کار تاکن...
it has been known that cardiomyocytes possess a remarkable ability to downregulate their energy expenditure on restricted 02 supply. however it has also been speculated that an ability to suppress aerobic respiration and atp utilization could be a protective response to prolonged hypoxia. having the role of the cytochrome oxidase enzyme in mind, one can ask if its inhibition by using cyanide ha...
b a ckground: anoph eles fluviatilis , one of the major malaria vectors in iran, is assumed to be a complex of sibling species. the aim of this study was to evaluate cytochrome oxidase i (coi) gene alongside 28s-d3 as a diagnostic tool for identification of an. fluviatilis sibling species in iran. m e t hods: dna sample belonging to 24 an. fluviatilis mosquitoes from different geographical area...
Identification of Intracellular Sources Responsible for Endogenous Reactive Oxygen Species Formation
The endogenous reactive oxygen species ("ROS") formation is associated with many pathologic states such as inflammatory diseases, neurodegenerative diseases, brain and heart ischemic injuries, cancer, and aging. The purpose of this study was to investigate the endogenous sources for "ROS" formation in intact isolated rat hepatocytes, in particular, peroxisomal oxidases, monoamine oxidase, xanth...
The reaction of the electrostatic cytochrome c-cytochrome oxidase complex with oxygen is measured by transient absorption spectroscopy. The oxygen reaction is initiated by photolytic removal of CO from cytochrome oxidase, using a flash-pumped dye laser. The subsequent reaction of the cytochrome c-cytochrome oxidase complex with oxygen is reported at 550, 605, 744, and 830 nm at different cytoch...
چکیده تعداد گونه های قارچی موجود حدود 5/1 میلیون عدد برآورد شده است که تا امروز کمتر از 10 درصد آنها توصیف شده اند. با پیشرفت های اخیر در زیست شناسی مولکولی و توسعه فناوری هایی مثل توالی یابی ژنی و ژنومی، کشف و شناسایی گونه های جدید در گروه های مختلف موجودات زنده به ویژه قارچ ها روند افزایشی به خود گرفته است. با توجه به ناکارآمدی روش های مبتنی بر ریخت شناسی برای شناسایی گونه های قارچی، استفاده ...

Although the terminal respiratory chain of Azotobacter has been the subject of several recent studies, the nature of the cytochrome oxidase portion is still somewhat obscure. Repaske (1) partially purified and characterized a soluble succinic dehydrogenase and succinoxidase system from Azotobacter z&elan&i. Wilson and Wilson (2) studied the soluble succinoxidase in Repaske’s preparation and dem...
The iron-oxidizing bacterium Acidithiobacillus ferrooxidans MON-1 is highly resistant not only to mercuric chloride (HgCl(2)) but also to organomercurials such as methylmercury chloride (MMC). We have found that cytochrome c oxidase, purified from strain MON-1, reduces Hg(2+) to volatilizable metal mercury (Hg(0)) with reduced mammalian cytochrome c or Fe(2+) as an electron donor. In this study...
