DNA binding protein from ovaries of the frog, Xenopus laevis which promotes concatenation of linear DNA.

Abstract

A soluble extract of Xenopus laevis ovaries catalyzed ATP-dependent concatenation of linear duplex DNA molecules. DNA ligase and a unique X. laevis DNA binding protein were required for the formation of concatemers. A linear DNA concatenation system was reconstituted using T4 DNA ligase and homogeneous X. laevis DNA binding protein. This system catalyzed intermolecular ligation of DNA molecules into linear concatemers of up to ten or more times monomer length.
