Bacteriophage T4 deoxynucleotide kinase: gene cloning and enzyme purification.

RESUMO
Gene 1 of bacteriophage T4 has been cloned into a lambda pL expression vector, resulting in the overproduction of deoxynucleotide kinase. A procedure that includes affinity chromatography on Cibacron Blue F3GA-agarose has been used to purify milligram quantities of enzymes from a 2-liter culture. The enzyme has been partially characterized in vitro and in vivo, and it appears to be identical to the deoxynucleotide kinase isolated from T4-infected Escherichia coli. These results prove the earlier contention that the phosphorylation of three dissimilar deoxynucleotides (5-hydroxymethyldeoxycytidylate, dTMP, and dGMP), to the exclusion of most others, is catalyzed by a single protein.
