molecular function |
| GO:0005525 | | GTP binding | | Interacting selectively and non-covalently with GTP, guanosine triphosphate. |
| GO:0004081 | | bis(5'-nucleosyl)-tetraphosphatase (asymmetrical) activity | | Catalysis of the reaction: P(1),P(4)-bis(5'-nucleosyl)tetraphosphate + H2O = NTP + NMP. Acts on bis(5'-guanosyl)-, bis(5'-xanthosyl)-, bis(5'-adenosyl)- and bis(5'-uridyl)-tetraphosphate. |
| GO:0008803 | | bis(5'-nucleosyl)-tetraphosphatase (symmetrical) activity | | Catalysis of the reaction: P(1),P(4)-bis(5'-adenosyl) tetraphosphate + H(2)O = 2 ADP + 2 H(+). |
| GO:0008796 | | bis(5'-nucleosyl)-tetraphosphatase activity | | Catalysis of the hydrolysis of P(1),P(4)-bis(5'-nucleosyl)tetraphosphate into two nucleotides. |
| GO:0016787 | | hydrolase activity | | Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3. |
| GO:0000166 | | nucleotide binding | | Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose. |
| GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
biological process |
| GO:0006915 | | apoptotic process | | A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by 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. |
| GO:0006139 | | nucleobase-containing compound metabolic process | | Any cellular metabolic process involving nucleobases, nucleosides, nucleotides and nucleic acids. |
| GO:0000302 | | response to reactive oxygen species | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a reactive oxygen species stimulus. Reactive oxygen species include singlet oxygen, superoxide, and oxygen free radicals. |
cellular component |
| GO:0005759 | | mitochondrial matrix | | The gel-like material, with considerable fine structure, that lies in the matrix space, or lumen, of a mitochondrion. It contains the enzymes of the tricarboxylic acid cycle and, in some organisms, the enzymes concerned with fatty acid oxidation. |
| GO:0005739 | | mitochondrion | | A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration. |
