DNA primase. Processivity and the primase to polymerase alpha activity switch.
Calf thymus DNA primase was examined to determine the kinetic parameters that define its unusual processivity. At 37 degrees C, the major products were 8-9 and 2-3 nucleotides long. The 2-mer was theExpand

Multiple roles of divalent cation in the terminal deoxynucleotidyltransferase reaction.
Terminal deoxynucleotidyltransferase activity is absolutely dependent on the presence of a divalent cation in the reaction mixture. This requirement can be satisfied by either Mg2+, Co2+, or Mn2+.Expand

Molecular biology of terminal transferase.
Terminal transferase is an unusual deoxynucleotide polymerizing enzyme found only in prelymphocytes. The protein was purified to homogeneity from calf thymus glands in 1971 as a 32 kDa protein with aExpand

Expression of human terminal deoxynucleotidyl transferase in Escherichia coli.
A cloned DNA fragment related to pT17 containing a partial cDNA sequence of human terminal deoxynucleotidyl transferase was used as a probe to screen for the full length cDNA sequence of the enzymeExpand
