Polymerase — Structure of Taq DNA polymerase A polymerase (EC 2.7.7.6/7/19/48/49) is an enzyme whose central function is associated with polymers of nucleic acids such as RNA and DNA. The primary function of a polymerase is the polymerization of new DNA or… … Wikipedia
RNA polymerase — RNAP from T. aquaticus pictured during elongation. Portions of the enzyme were made transparent so as to make the path of RNA and DNA more clear. The magnesium ion (yellow) is located at the enzyme active site. RNA polymerase (RNAP or RNApol) is… … Wikipedia
DNA polymerase — 3D structure of the DNA binding helix turn helix motifs in human DNA polymerase beta A DNA polymerase is an enzyme that helps catalyze in the polymerization of deoxyribonucleotides into a DNA strand. DNA polymerases are best known for their… … Wikipedia
Primase — DNA primase is an enzyme involved in the replication of DNA. Primase catalyzes the synthesis of a short RNA (or DNA in some organisms [1]) segment called a primer complementary to a ssDNA template. Primase is of key importance in DNA replication… … Wikipedia
Helicase — Structure of E. coli helicase RuvA Helicases are a class of enzymes vital to all living organisms. They are motor proteins that move directionally along a nucleic acid phosphodiester backbone, separating two annealed nucleic acid strands (i.e.,… … Wikipedia
DNA polymerase I — Functional domains in the Klenow Fragment (left) and DNA Polymerase I (right). DNA Polymerase I (or Pol I) is an enzyme that participates in the process of DNA replication in prokaryotes. It is composed of 928 amino acids, and is an example of a… … Wikipedia
