We describe the first enzymatic incorporation of an α-L-LNA nucleotide into an oligonucleotide. It was found that the 5'-triphosphate of α-L-LNA is a substrate for the DNA polymerases KOD, 9°N(m), Phusion and HIV RT. Three dispersed α-L-LNA thymine nucleotides can be incorporated into DNA strands by all four polymerases, but they were unable to perform consecutive incorporations of α-L-LNA nucleotides. In addition it was found that primer extension can be achieved using templates containing one α-L-LNA nucleotide.
我们描述了首次将α-L-锁核酸核苷酸酶促掺入寡核苷酸的过程。发现α-L-锁核酸的5'-三磷酸是DNA聚合酶KOD、9°N(m)、Phusion和HIV逆转录酶的底物。所有这四种聚合酶均可将三个分散的α-L-锁核酸胸腺嘧啶核苷酸掺入DNA链中，但它们无法连续掺入α-L-锁核酸核苷酸。此外，还发现使用含有一个α-L-锁核酸核苷酸的模板可实现引物延伸。
