Abstract

Bacteriophage T4 gene 32 coded protein (gp32) was isolated by Alberts and coworkers (1,2,3). It binds tightly, cooperatively and preferentially to single-stranded DNA. It facilitates both the denaturation and the renaturation of DNA. Genetic studies have demonstrated that this protein is essential for genetic recombination (4), DNA replication (5), repair of radiation damaged DNA (6), and protection of replicating T4 chromosome from degradative activities (7,8). In vitro, gp32 enhances the rate at which T4 DNA polymerase utilizes single-stranded DNA temperates by 5 to 10-fold (9). Gp32 is also one of the essential components of the reconstructed DNA replicating apparatus (11).
