NCBI and Uniprot Product Information
NCBI Description
gyrA is an essential gene. [More information is available at EcoGene: EG10423]. DNA gyrase is one of two essential members of the type II topoisomerase family in Escherichia coli. [More information is available at EcoCyc: EG10423].
Uniprot Description
A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to maintain chromosomes in an underwound state (PubMed:3031051, PubMed:186775, PubMed:7811004, PubMed:9148951, PubMed:12051842, PubMed:18642932, PubMed:19060136, PubMed:20356737, PubMed:22457353, PubMed:23294697, PubMed:19965760). This makes better substrates for topoisomerase IV (ParC and ParE) which is the main enzyme that unlinks newly replicated chromosomes in E.coli (PubMed:9334322). Gyrase catalyzes the interconversion of other topological isomers of dsDNA rings, including catenanes (PubMed:22457352). Relaxes negatively supercoiled DNA in an ATP-independent manner (PubMed:337300). E.coli gyrase has higher supercoiling activity than many other bacterial gyrases; at comparable concentrations E.coli gyrase introduces more supercoils faster than M.tuberculosis gyrase, while M.tuberculosis gyrase has higher decatenation than supercoiling activity compared to E.coli (PubMed:22457352). E.coli makes 15% more negative supercoils in pBR322 plasmid DNA than S.typhimurium; the S.typhimurium GyrB subunit is toxic in E.coli, while the E.coli copy can be expressed in S.typhimurium even though the 2 subunits have 777/804 residues identical (PubMed:17400739). The enzymatic differences between E.coli gyrase and topoisomerase IV are largely due to the GyrA C-terminal domain (approximately residues 524-841) and specifically the GyrA-box (PubMed:8962066, PubMed:16332690).

Product Notes
The gyrA gyra (Catalog #AAA7166264) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Rabbit anti-Escherichia coli (strain K12) gyrA Polyclonal Antibody reacts with E Coli (strain K12) and may cross-react with other species as described in the data sheet. AAA Biotech's gyrA can be used in a range of immunoassay formats including, but not limited to, ELISA (EIA), WB (Western Blot) (ensure identification of antigen). Researchers should empirically determine the suitability of the gyrA gyra for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "gyrA, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
