2.7.7.19 | C36S/C118V/A152C/C160S/C197S/C257S/C293S/C204V |
introduction of a Cys residue in a mutant lacking all endogenous Cys residues. Mutant achieves maximum specific disulfide cross-linking efficiency. The resulting construct is active and, when mixed with a chemically modified RNA, yields crystals of an enzyme-RNA complex |
721206 |
2.7.7.19 | C36S/C118V/C160S/C197S/C257S/C293S/C204V |
mutation of all seven endogenous cysteine residues. Mutant is able to bind RNA at a level similar to that of wild-type, but no longer forms nonspecific disulfide cross-links with the modified RNA |

2.7.7.19 | D114A |
polyadenylation-defective mutant |
761749 |
2.7.7.19 | D124A |
the mutant shows strongly reduced activity compared to the wild type enzyme |
762055 |
2.7.7.19 | D126A |
the mutant shows strongly reduced activity compared to the wild type enzyme |
