| molecular function |
| | 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:0004518 | | nuclease activity | | Catalysis of the hydrolysis of ester linkages within nucleic acids. |
| biological process |
| | GO:0006952 | | defense response | | Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack. |
| | GO:0042742 | | defense response to bacterium | | Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism. |
| | GO:0050832 | | defense response to fungus | | Reactions triggered in response to the presence of a fungus that act to protect the cell or organism. |
| | GO:0031640 | | killing of cells of other organism | | Any process in an organism that results in the killing of cells of another organism, including in some cases the death of the other organism. Killing here refers to the induction of death in one cell by another cell, not cell-autonomous death due to internal or other environmental conditions. |
| | GO:0090305 | | nucleic acid phosphodiester bond hydrolysis | | The nucleic acid metabolic process in which the phosphodiester bonds between nucleotides are cleaved by hydrolysis. |
| | GO:0009626 | | plant-type hypersensitive response | | The rapid, localized death of plant cells in response to invasion by a pathogen. |
| | GO:0009607 | | response to biotic stimulus | | 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 biotic stimulus, a stimulus caused or produced by a living organism. |
