EOG8B2WGK GO:0006260 1/3 DNA replication biological_process "The cellular metabolic process in which a cell duplicates one or more molecules of DNA. DNA replication begins when specific sequences, known as origins of replication, are recognized and bound by initiation proteins, and ends when the original DNA molecule has been completely duplicated and the copies topologically separated. The unit of replication usually corresponds to the genome of the cell, an organelle, or a virus. The template for replication can either be an existing DNA molecule or RNA." [GOC:mah] EOG8B2WGK GO:0003700 1/3 transcription factor activity, sequence-specific DNA binding molecular_function "Interacting selectively and non-covalently with a specific DNA sequence in order to modulate transcription. The transcription factor may or may not also interact selectively with a protein or macromolecular complex." [GOC:curators, GOC:txnOH] EOG8B2WGK GO:0003678 1/3 DNA helicase activity molecular_function "Catalysis of the reaction: NTP + H2O = NDP + phosphate, to drive the unwinding of a DNA helix." [GOC:jl, GOC:mah] EOG8B2WGK GO:0006352 1/3 DNA-templated transcription, initiation biological_process "Any process involved in the assembly of the RNA polymerase preinitiation complex (PIC) at the core promoter region of a DNA template, resulting in the subsequent synthesis of RNA from that promoter. The initiation phase includes PIC assembly and the formation of the first few bonds in the RNA chain, including abortive initiation, which occurs when the first few nucleotides are repeatedly synthesized and then released. The initiation phase ends just before and does not include promoter clearance, or release, which is the transition between the initiation and elongation phases of transcription." [GOC:jid, GOC:txnOH, PMID:18280161] EOG8B2WGK GO:0016987 1/3 sigma factor activity molecular_function "A sigma factor is the promoter specificity subunit of eubacterial-type multisubunit RNA polymerases, those whose core subunit composition is often described as alpha(2)-beta-beta-prime. (This type of multisubunit RNA polymerase complex is known to be found in eubacteria and plant plastids). Although sigma does not bind DNA on its own, when combined with the core to form the holoenzyme, this binds specifically to promoter sequences, with the sigma factor making sequence specific contacts with the promoter elements. The sigma subunit is released from the elongating form of the polymerase and is thus free to act catalytically for multiple RNA polymerase core enzymes." [GOC:krc, GOC:txnOH] EOG8B2WGK GO:0003677 1/3 DNA binding molecular_function "Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid)." [GOC:dph, GOC:jl, GOC:tb, GOC:vw] EOG8B2WGK GO:0005524 1/3 ATP binding molecular_function "Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator."
