EOG8QC3KN GO:0016491 28/101 oxidoreductase activity molecular_function "Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced." [GOC:go_curators] EOG8QC3KN GO:0046872 28/101 metal ion binding molecular_function "Interacting selectively and non-covalently with any metal ion." [GOC:ai] EOG8QC3KN GO:0051537 28/101 2 iron, 2 sulfur cluster binding molecular_function "Interacting selectively and non-covalently with a 2 iron, 2 sulfur (2Fe-2S) cluster; this cluster consists of two iron atoms, with two inorganic sulfur atoms found between the irons and acting as bridging ligands." [GOC:ai, PMID:15952888, Wikipedia:Iron-sulfur_cluster] EOG8QC3KN GO:0050660 28/101 flavin adenine dinucleotide binding molecular_function "Interacting selectively and non-covalently with FAD, flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes, in either the oxidized form, FAD, or the reduced form, FADH2." [CHEBI:24040, GOC:ai, GOC:imk, ISBN:0198506732] EOG8QC3KN GO:0045454 27/101 cell redox homeostasis biological_process "Any process that maintains the redox environment of a cell or compartment within a cell." [GOC:ai, GOC:dph, GOC:tb] EOG8QC3KN GO:0008860 2/101 ferredoxin-NAD+ reductase activity molecular_function "Catalysis of the reaction: reduced ferredoxin + NAD+ = oxidized ferredoxin + NADH + H+." [EC:1.18.1.3] EOG8QC3KN GO:0097194 1/101 execution phase of apoptosis biological_process "A stage of the apoptotic process that starts with the controlled breakdown of the cell through the action of effector caspases or other effector molecules (e.g. cathepsins, calpains etc.). Key steps of the execution phase are rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died." [GOC:mtg_apoptosis, PMID:21760595] EOG8QC3KN GO:0005783 1/101 endoplasmic reticulum cellular_component "The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached)."
