Name DNA nucleotidylexotransferase
Description Not Available
Synonyms
  1. Terminal addition enzyme
  2. Terminal deoxynucleotidyltransferase
  3. Terminal transferase
Gene Name DNTT
Protein Type Enzyme
Biological Properties
General Function Involved in DNA binding
Specific Function Template-independent DNA polymerase which catalyzes the random addition of deoxynucleoside 5'-triphosphate to the 3'-end of a DNA initiator. One of the in vivo functions of this enzyme is the addition of nucleotides at the junction (N region) of rearranged Ig heavy chain and T-cell receptor gene segments during the maturation of B- and T-cells.
