Bacteriophage PRD1 DNA polymerase: evolution of DNA polymerases.

Abstract

A small lipid-containing bacteriophage PRD1 specifies its own DNA polymerase that utilizes terminal protein as a primer for DNA synthesis. The PRD1 DNA polymerase gene has been sequenced, and its amino acid sequence has been deduced. This protein-primed DNA polymerase consists of 553 amino acid residues with a calculated molecular weight of 63,300. Thus, it… (More)
