| molecular function |
|---|
| | GO:0005524 | | ATP binding | | Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
| | GO:0003677 | | DNA binding | | Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid). |
| | GO:0034335 | | DNA supercoiling activity | | Catalytic introduction of supercoils in a DNA molecule or region thereof. In bacteria, negative supercoils are only introduced by DNA gyrase, a type II topoisomerase, but not all DNA gyrases are capable of introducing supercoils. In bacteria, the level of supercoiling varies widely between species and has been characterized properly in only a handful of organisms. The best characterized enzyme, from E.coli, is exceptionally proficient at supercoiling and this ability is not representative of all bacteria. |
| | GO:0003916 | | DNA topoisomerase activity | | Catalysis of the transient cleavage and passage of individual DNA strands or double helices through one another, resulting a topological transformation in double-stranded DNA. |
| | GO:0003918 | | DNA topoisomerase type II (ATP-hydrolyzing) activity | | Catalysis of a DNA topological transformation by transiently cleaving a pair of complementary DNA strands to form a gate through which a second double-stranded DNA segment is passed, after which the severed strands in the first DNA segment are rejoined; product release is coupled to ATP binding and hydrolysis; changes the linking number in multiples of 2. |
| | GO:0016853 | | isomerase activity | | Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5. |
| | GO:0000287 | | magnesium ion binding | | Interacting selectively and non-covalently with magnesium (Mg) ions. |
| | 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:0006259 | | DNA metabolic process | | Any cellular metabolic process involving deoxyribonucleic acid. This is one of the two main types of nucleic acid, consisting of a long, unbranched macromolecule formed from one, or more commonly, two, strands of linked deoxyribonucleotides. |
| | GO:0006265 | | DNA topological change | | The process in which a transformation is induced in the topological structure of a double-stranded DNA helix, resulting in a change in linking number. |
| | GO:0006268 | | DNA unwinding involved in DNA replication | | The process in which interchain hydrogen bonds between two strands of DNA are broken or 'melted', generating unpaired template strands for DNA replication. |
| | GO:0006261 | | DNA-dependent DNA replication | | A DNA replication process that uses parental DNA as a template for the DNA-dependent DNA polymerases that synthesize the new strands. |
| | GO:0007059 | | chromosome segregation | | The process in which genetic material, in the form of chromosomes, is organized into specific structures and then physically separated and apportioned to two or more sets. In eukaryotes, chromosome segregation begins with the condensation of chromosomes, includes chromosome separation, and ends when chromosomes have completed movement to the spindle poles. |
| | GO:0046677 | | response to antibiotic | | 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 an antibiotic stimulus. An antibiotic is a chemical substance produced by a microorganism which has the capacity to inhibit the growth of or to kill other microorganisms. |
| cellular component |
|---|
| | GO:0009330 | | DNA topoisomerase complex (ATP-hydrolyzing) | | Complex that possesses DNA topoisomerase (ATP-hydrolyzing) activity. |
| | GO:0005618 | | cell wall | | The rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal, most prokaryotic cells and some protozoan parasites, maintaining their shape and protecting them from osmotic lysis. In plants it is made of cellulose and, often, lignin; in fungi it is composed largely of polysaccharides; in bacteria it is composed of peptidoglycan; in protozoan parasites such as Giardia species, it's made of carbohydrates and proteins. |
| | GO:0005694 | | chromosome | | A structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information. |
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0009295 | | nucleoid | | The region of a virus, bacterial cell, mitochondrion or chloroplast to which the nucleic acid is confined. |
| | GO:0005886 | | plasma membrane | | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
