  • GO:0045892 Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.
  • GO:0006508 The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.
  • GO:0006355 Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
  • GO:0004252 Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a catalytic mechanism that involves a catalytic triad consisting of a serine nucleophile that is activated by a proton relay involving an acidic residue (e.g. aspartate or glutamate) and a basic residue (usually histidine).
  • GO:0009432 An error-prone process for repairing damaged microbial DNA.
  • GO:0003677 Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
  • GO:0006281 The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway.
  • GO:0006260 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 the origin recognition complex, 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.
