WebTranscription takes nucleosomes by RNA consumer (RNAP) is joined at formation of narrow intranucleosomal DNA loops (i-loops). The i-loops form more efficiently in the presence of single-strand breaks conversely gaps in one non-template DNA strand (NT-SSBs) and induce catch of transcribing RNAP, thus allowing detection of NT-SSBs by who enzyme. … WebDec 20, 2005 · Function.

Did you know?
Topoisomerase IV is one of two Type II topoisomerases in bacteria, the other being DNA gyrase. Like gyrase, topoisomerase IV is able to pass one double-strand of DNA through another double-strand of DNA, thereby changing the linking number of DNA by two in each enzymatic step. Both share a hetero-4-mer … See more Topoisomerase IV has two functions in the cell. • First, it is responsible for unlinking, or decatenating, DNA following DNA replication.

The antibiotic sulfonamides prevent bacteria from producing folic acid by competing with para-aminobenzoic acid (PABA) for the enzyme dihydropteroate synthase.
WebUpon protein-denaturant treatment, the phosphodiester bond of DNA is cleaved, and the gene 52 protein subunit of the topoisomerase becomes covalently linked to the 5'-end of the broken DNA. The covalent protein-DNA linkage has been determined by both paper electrophoresis and thin layer chromatography to be tyrosyl phosphate.
