The Taq DNA polymerase is the most commonly used enzyme in DNA sequencing. However, all versions of Taq polymerase are deficient in two respects: (i) these enzymes incorporate each of the four dideoxynucleoside 5' triphosphates (ddNTPs) at widely different rates

The ribonucleoprotein telomerase, a specialized cellular reverse transcriptase, synthesizes one strand of the telomeric DNA of eukaryotes. We analyzed telomere maintenance in two immortalized human cell lines: the B-cell line JY616 and the T-cell line Jurkat E6-1, and determined whether
The identification of methylated sites on bacterial genomic DNA would be a useful tool to study the major roles of DNA methylation in prokaryotes: distinction of self and nonself DNA, direction of post-replicative mismatch repair, control of DNA replication and

Many bacterial expression systems have been developed to study the reverse transcriptase (RT) of human immunodeficiency virus type 1 (HIV-1). This enzyme exists in the virions as a heterodimer of a 66 kDa (p66) subunit and a 51 kDa (p51)

Determination of the three-dimensional structure of the human immunodeficiency virus type-1 (HIV-1) reverse transcriptase (RT) has indicated a totally different folding for the 51-kDa subunit (p51) than for the 66-kDa subunit (p66). The polymerase catalytic site is located on the
