15 صفحه اولThe synthesis of oligodeoxyribonucleotides using RNA ligase.
T4 RNA ligase catalyzes the addition of a single deoxyribonucleoside 3',5'-bisphosphate to the 3'-hydroxyl of oligodeoxyribonucleotides (Hinton et al. (1978) Biochemistry 17, 5091). We have determined improved conditions for this reaction which give yields equal to or greater than 85% when any of five common deoxyribonucleoside bisphosphate (pdAp, pdCp, pdGp, pdTp, or pdUp) are added to dA(PDA)...
متن کاملThe preparative synthesis of oligodeoxyribonucleotides using RNA ligase.
The synthesis of nmol quantities of defined sequences of oligodeoxyribonucleotides using T4 RNA ligase has been demonstrated. Reacting using from 18 to 200 nmol of substrates in which a single 2'-deoxyribonucleoside 3',5'-bisphosphate was added to an oligodeoxyribonucleotide resulted in yields from 13 to 95%. When two oligodeoxyribonucleotides were similarly joined using RNA ligase, the yields ...
متن کاملChemical synthesis and papain-catalysed hydrolysis of N-alpha-benzyloxycarbonyl-L-lysine p-nitroanilide.
The chemical synthesis of N-alpha-benzyloxycarbonyl-L-lysine p-nitroanilide (Z-Lys-pNA) is described in detail. The pH-dependence of the catalytic parameters kcat,' Km and kcat./Km for the papain-catalysed hydrolysis of Z-Lys-pNA are determined. kcat. and Km are pH-independent between pH 5 and pH 7.42, but the pH-dependence of kcat./Km is bell-shaped, decreasing at high and low pH values with p...
متن کاملRapid synthesis of oligodeoxyribonucleotides. IV. Improved solid phase synthesis of oligodeoxyribonucleotides through phosphotriester intermediates.
A phosphotriester solid phase method on a polyamide support has been used to prepare oligodeoxyribonucleotides up to 12 units long. Compared to solid phase phosphodiester synthesis the new methodology is quicker, more flexible and gives 10-60-fold better overall yields.
