摘要：

Several years ago, we published an hypothesis concerning conformation of the glycone moiety of different substrates in active centers of several DNA metabolizing enzymes (Nucleosides & Nucleotides 1993, 12, 649-670). This hypothesis prompted us to further study the subtle conformational changes on substrates of DNA polymerases. Data collected in our, as well as other laboratories, have been analyzed, and models of active centers of different DNA polymerases are discussed below. Based on the model of substrate requirements, we now can divide DNA polymerases into two distinguished classes.
