Structural requirements for binding of bovine tRNATrp with avian myeloblastosis virus DNA polymerase.
Avian DNA polymerases use host tRNATrp as the primer for transcription. Bovine tRNATrp has been previously shown to be a biologic substitute for the avian primer. A bovine tRNATrp fragment has been identified as having a high binding affinity for the polymerase. The fragment is assigned to be 67 nucleotides, and contains most of the elements required to maintain the secondary and tertiary structure of tRNATrp.
