- ID: EG10686
- Name: parC
- Organism: E. coli
- UniProt ID: P0AFI2
- Description: parC codes for the alpha subunit of DNA topoisomerase IV in E. coli. DNA topoisomerase IV consists of two alpha subunits and two beta subunits. The beta subunits are coded for by parE. Topoisomerases are a vital group of proteins that deal with DNA topology. DNA topoisomerase IV aids mainly in regulating DNA topology during DNA replication UniProt. Well executed DNA replication is necessary for meiosis and cell reproduction. Topoisomerase IV ensures the decatenating, or unlinking, of newly replicated DNA strands and chromosomes. Separation of chromosomes is essential for chromosome segregation and proper cellular reproduction. Topoisomerase IV also relaxes supercoiled DNA. NIH.

Function and Homologs
- Functional Category: DNA Topology
- Product: DNA topoisomerase IV, A subunit
- Module: DNA topoisomerase
- Closest homologous proteins:
- Expression Level: medium
- Expression Level Hypothesis: parC is likely expressed at a medium level in E. coli because it codes for the alpha subunit of DNA Topoisomerase IV, a protein that is essential for chromosome segregation, a key step of cell division.
- Expression Level References and Description: E. coli proteome data
- Expression Time: late
- Expression Time Hypothesis: As the protein this gene, parC, codes for is only really required to facilitate separation of the chromosomes after genome replication, it is only required for cellular division and thus can be expressed late in the reaction.
- Expression Time References and Description: UniProt
- Other Components: DNA Topoisomerase IV, B subunit. The B subunit of this protein is coded for by the parE gene. Two alpha subunits and two beta subunits form the complete DNA Topoisomerase IV enzyme
- Possible Dependencies: DNA polymerases 1 and 3 are necessary for DNA replication and DNA Topoisomerase IV is active after replication.
- Process: The main process DNA Topoisomerase IV takes part in is decatenating daughter strands following DNA replication. The enzyme takes the linked daughter strands and removes the linkages to have two separate DNA segments. This is crucial for chromosome segregation in cell division.
- Inputs: Linked Daughter DNA strands, ATP
- Outputs: Unlinked Daughter DNA strands
