Abstract: | The simplest variant of synthetic substrate-ribozyme complex has been proposed. The schemes of potential ribozyme "subunits" synthesis have been worked out: R1--GCUUGAAACAAA; R2--AAAAACUGAUGAAAGC. The macroscale synthesis of dinucleoside monophosphate ApU, GpC, CpU catalyzed by immobilized ribonucleases of different specificity and preparation of oligoadenylates by hydrolysis of poly-A in the presence of endonuclease Serratia marcescens, as well the synthesis of conservative sequences of potential ribozyme such as ApUpG, CpUpG, GpApU, ApApApG and others have been described. |
