CC -!- FUNCTION: Template-independent DNA polymerase which catalyzes the
CC random addition of deoxynucleoside 5'-triphosphate to the 3'-end of a
CC DNA initiator. One of the in vivo functions of this enzyme is the
CC addition of nucleotides at the junction (N region) of rearranged Ig
CC heavy chain and T-cell receptor gene segments during the maturation of
CC B- and T-cells. {ECO:0000256|ARBA:ARBA00037135}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 2'-deoxyribonucleoside 5'-triphosphate + DNA(n) =
CC diphosphate + DNA(n+1); Xref=Rhea:RHEA:22508, Rhea:RHEA-COMP:17339,
