In the past, type IB topoisomerases were referred to as eukaryotic topoisomerase I, but IB topoisomerases are present in all three domains of life. Type IB topoisomerases form a covalent intermediate with the 3' end of DNA. Type IC topoisomerase (also called Topoisomerase V) has been identified.

Topoisomerases serve to maintain both the transcription and replication of DNA. Aside from topoisomerases I and II, there are more discovered topoisomerases. Topoisomerase III may regulate recombination while topoisomerase IV regulates the process of segregating newly replicated chromosomes from one another.

When DNA replication occurs, the DNA strand is being unwound, causing the DNA to be overwound tightly past the replication fork. For example, If you have ever wrapped two strings around each other and then tried to pull part the middle of the string while holding the ends tight, the rest of the string past the place you're pulling the string apart becomes very tight and strained.

DNA Topoisomerase By Jennifer McDowall The DNA in the nucleus of a cell contains all the information it requires to carry out life’s processes: growth, development, maintenance, reproduction and protection. With all this information, it is no wonder that the length of a cell’s DNA is far greater than that of the cell compartment that contains it - the DNA in a single human diploid cell ...

The focus of this tutorial is E. coli DNA topoisomerase I, responsible primarily for the relaxation of negative supercoils. Topoisomerase I has also been implicated in knotting and unknotting DNA and in linking complementary rings of single-stranded DNA into double-stranded rings.

DNA topoisomerase 1, topoisomerase (DNA) I, type I DNA topoisomerase. GeneRIFs: Gene References Into Functions. Results from a study on gene expression variability markers in early-stage human embryos shows that TOP1 is a putative expression variability marker for the 3-day, 8-cell embryo stage.

Autoantibodies targeted against type I topoisomerase are called anti-Scl-70 antibodies, named by the association with scleroderma and the 70 kD extractable immunoreactive fragment that can be obtained from the otherwise larger (100-105 kD) target topoisomerase antigen (called the SCL-70 Antigen) of the antibodies.

Difference Between Topoisomerase I and II www.differencebetween.com Key Difference - Topoisomerase I vs II DNA is needed by a cell in order to divide into two daughter cells by cell division. DNA is duplicated by DNA replication. So, there should be a special mechanism in order to replicate the highly wound spiraled DNA.
