| '''The crystal structure of the monomeric reverse transcriptase from Moloney murine leukemia virus'''<br />
| |
| | |
| ==Overview==
| |
| Reverse transcriptases (RTs) are multidomain enzymes of variable, architecture that couple both RNA- and DNA-directed DNA polymerase, activities with an RNase H activity specific for an RNA:DNA hybrid in, order to replicate the single-stranded RNA genome of the retrovirus., Previous structural work has been reported for the heterodimeric HIV-1 and, HIV-2 RTs. We now report the first crystal structure of the full-length, Moloney murine leukemia virus (MMLV) RT at 3.0 A resolution. The structure, reveals a clamp-shaped molecule resulting from the relative positions of, the thumb, connection, and RNase H domains that is strikingly different, from the HIV-1 RT and provides the first example of a monomeric reverse, transcriptase. A comparative analysis with related DNA polymerases, suggests a unique trajectory for the template-primer exiting the, polymerase active site and provides insights regarding processive DNA, synthesis by MMLV RT.
