WebFeb 14, 2024 · 1. Introduction. Cytochrome c oxidase, the terminal enzyme of the electron transport chain, is an indispensable part of mitochondrial machinery needed for ATP production in mammalian cells (OXPHOS). In addition to three mitochondria-encoded subunits, which are necessary for COX catalytic function, eleven nuclear-encoded … WebCytochrome c can be detected by ELISA in cell culture medium as early as one hour from induction of apoptosis7 in a non-radioactive lymphocyte killing assay, which is 3 hours faster than 51Cr release assay and 8 hours faster than DNA degradation tunnel assays. Cytochrome c is released from apoptotic cells and detectable in serum of anti cancer-drug
WebCytochrome c is a well conserved electron-transport protein and is part of the respiratory chain localized to mitochondrial intermembrane space (1). Upon apoptotic stimulation, cytochrome c released from mitochondria associates with procaspase-9 (47 kDa)/Apaf 1. This complex processes caspase-9 from inactive proenzyme to its active form (2). WebMar 1, 1987 · Abstract. Several heme aa 3-type cytochrome c oxidases, purified from the cytoplasmic membranes of bacteria, are able to catalyze the same reactions as the structurally far more complex eukaryotic enzyme, i.e., electron transport from cytochrome c to oxygen coupled to proton translocation. However, these oxidases show a very simple …
WebJun 29, 2024 · Cytochrome c (Cc) is well-known as an electron carrier at mitochondria but can also catalyze peroxidase-like reactions. Although the reported catalytic abilities are low, the role of Cc in transforming environmental toxicants requires additional studies. We employed cardiolipin vesicles to stimulate the enzymatic activity of Cc and tested the …
