Identified Protein:
gyrA (Escherichia coli K12 MG1655):   DNA gyrase (type II topoisomerase), subunit A; 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 interconversi [...]
