Genetic insertions and diversification of the PolB-type DNA polymerase (gp43) of T4-related phages.

Journal of molecular biology - 22 Jan 2010

Petrov Vasiliy M, Ratnayaka Swarnamala, Karam Jim D

Abstract excerpt

In Escherichia coli phage T4 and many of its phylogenetic relatives, gene 43 consists of a single cistron that encodes a PolB family (PolB-type) DNA polymerase. We describe the divergence of this phage gene and its protein product (gp43) (gene product 43) among 26 phylogenetic relatives of T4 and discuss our observations in the context of diversity among the widely distributed PolB enzymes in nature. In two T4...
