pubmed-article:673838 | pubmed:abstractText | 2'-Deoxy-2'-fluoroadenosine was chemically transformed to its 5'-diphosphate and polymerized with polynucleotide phosphorylase to give poly(2'-deoxy-2'-fluoroadenylic acid) [poly(Af)]. Polymerization proceeded smoothly as in the case of poly(A) and the yield of the polymerization was 55%. The UV absorption spectra of poly(Af) closely resembled those of poly(A) and the hypochromicity was 32% at pH 7.0. The CD profile at 25 degrees and neutrality showed similar pattern to that of other poly(2'-deoxy-2'-halogenoadenylic acids) with somewhat larger [theta] values both in the positive and negative maxima. Acid titration of poly(Af) showed a transition point at pH 5.2 and the Tm of the acid form was 37 degrees which was significantly lower than that of poly(A), but similar to that of poly(2'-azido-2'-deoxyadenylic acid). Poly(Af) formed 1:1 and 1:2 complexes with poly-(U) having Tm of 49 degrees and 62 degrees at 0.04M and 0.15M Na(+) concentration, respectively. Poly(Af) also formed a 1:2 complex with poly(I) and its Tm was 36 degrees at 0.05M Na(+) concentration. These data showed that poly(Af) has rather similar properties to those of poly(A), but not to poly(dA). | lld:pubmed |
