Role of mitochondrial inner membrane organizing system in protein biogenesis of the mitochondrial outer membrane
Mitochondria contain two membranes, the outer membrane and the inner membrane with folded cristae. The mitochondrial inner membrane organizing system (MINOS) is a large protein complex required for maintaining inner membrane architecture. MINOS interacts with both preprotein transport machineries of the outer membrane, the translocase of the outer membrane (TOM) and the sorting and assembly mac...
متن کاملAssembly of the mitochondrial membrane system. Sequences of yeast mitochondrial tRNA genes.
Two cytoplasmic "petite" (rho-) clones of Saccharomyces cerevisiae have been selected for the retention of the aspartic acid tRNA gene. The two clones, designated DS200/A102 and DS200/A5, have tandemly repeated segments of mitochondrial DNA (mtDNA) with unit lengths of 1,000 and 6,400 base pairs, respectively. The DS200/A102 genome has a single tRNA gene with a 3'-CUG-5' anticodon capable of re...
متن کاملAssembly of the mitochondrial membrane system: partial sequence of a mitochondrial ATPase gene in Saccharomyces cerevisiae.
The nucleotide sequence of mitochondrial DNA of a cytoplasmic "petite" mutant of Saccharomyces cerevisiae is reported. The DNA has a repeat length of 1060 base pairs and contains a genetic marker (oli-1) for the ATPase proteolipid. The nucleotide sequence reveals the presence of part of the structural gene of the subunit-9 proteolipid of the ATPase complex and an extended A+T-rich region adjace...
متن کاملThe effect of aminoguanidine on sperm motility and mitochondrial membrane potential in varicocelized rats
Objective(s): Increased levels of nitric oxide (NO) in the testicular veins of people suffering from varicocele have already been reported. However, the role of NO-synthase (NOS) isozymes and their inhibitors have not been extensively studied. We aimed to evaluate the inhibitory effects of aminoguanidine (AG), on sperm motility, vitality, and mitochondrial membrane potential (MMP) in varicoceli...
متن کاملThe Reversal of Mitochondrial Membrane
An electron microscope study of mitochondria in hamster liver and kidney cells has revealed that at some points the outer membrane of these organelles is continuous with the inner membrane. Also, at such points the discontinuous components of the membrane pairs have free endings. The outer and the inner membranes of a mitochondrion, therefore, may not be two different and distinct entities, as ...
