August undefined, 2024

DNA primase is an enzyme involved in the replication of DNA and is a type of RNA polymerase. Primase catalyzes the synthesis of a short RNA (or DNA in some living organisms ) segment called a primer complementary to a ssDNA (single-stranded DNA) template. After this elongation, the RNA piece is removed by … Visa mer In bacteria, primase binds to the DNA helicase forming a complex called the primosome. Primase is activated by the helicase where it then synthesizes a short RNA primer approximately 11 ±1 nucleotides long, … Visa mer There are two main types of primase: DnaG found in most bacteria, and the AEP (Archaeo-Eukaryote Primase) superfamily found in archaean … Visa mer • Overview article on primase structure and function (1995) • DNA+Primase at the U.S. National Library of Medicine Medical Subject Headings (MeSH) Visa mer The AEP family of primase-polymerases has diverse features beyond making only primers.
