TNA synthesis by DNA polymerases.
Threose nucleic acid (TNA), which has a repeat unit one atom shorter than that of DNA, is capable of Watson-Crick base pairing with DNA, RNA, and TNA. Because of its chemical simplicity, TNA is considered to be a possible progenitor of RNA. As an initial step toward developing the molecular tools necessary to investigate the functional capabilities of TNA by in vitro selection, we have screened...
متن کاملHigh fidelity TNA synthesis by Therminator polymerase
Therminator DNA polymerase is an efficient DNA-dependent TNA polymerase capable of polymerizing TNA oligomers of at least 80 nt in length. In order for Therminator to be useful for the in vitro selection of functional TNA sequences, its TNA synthesis fidelity must be high enough to preserve successful sequences. We used sequencing to examine the fidelity of Therminator-catalyzed TNA synthesis a...
متن کاملAn in Vitro Selection System for TNA
(3'-2')-alpha-l-Threose nucleic acid (TNA) is an unnatural polymer that possesses the rare ability to base-pair with RNA, DNA, and itself. This feature, coupled with its chemical simplicity, makes TNA of interest as a possible progenitor of RNA during the early history of life. To evaluate the functional potential of TNA, we have developed a system for the in vitro selection of TNA. We identifi...
متن کاملDNA polymerase-mediated DNA synthesis on a TNA template.
TNA, or threose nucleic acid, is capable of Watson-Crick base pairing with DNA, RNA, and TNA; coupled with its chemical simplicity, this suggests that TNA is a possible progenitor of RNA. As an initial step toward developing the molecular tools necessary to investigate the functional capabilities of TNA by in vitro selection, we have screened a variety of DNA polymerases for activity on a TNA t...
متن کاملIdentification of enterotoxin E.
Identification of a new enterotoxin was accomplished by purification of the enterotoxin produced by staphylococcal strain FRI-326 and by preparation of specific antitoxin to the enterotoxin. Toxicity of the preparations was determined in rhesus monkeys, and specificity of the enterotoxin-antitoxin reaction was determined in gel diffusion plates. The enterotoxin was designated enterotoxin E.
