F. Marciacq et al., Synthesis and enzymatic incorporation of morpholino thymidine-5 '-triphosphate in DNA fragments, TETRAHEDR L, 40(25), 1999, pp. 4673-4676
4-(carboxymethyl)-2-(thymidin-9-yl)-6-(hydroxymethyl)morpholine-6-triphosph
ate (morpholino thymidine-5'-triphosphate) was synthesised from 1-(beta-D-e
rythro-pentofuranosyl) thymine. It was fully characterised by NMR, UV and m
ass spectrometry. Taq polymerase enzymatic incorporation of this nucleotide
analogue into DNA fragments was investigated. Morpholino thymidine-5'-trip
hosphate was incorporated in a base-specific process and acted as a novel c
hain terminator in DNA sequencing, similarly to the corresponding dideoxynu
cleotide. (C) 1999 Elsevier Science Ltd. All rights reserved.
