genetic ablation of MT57 is compatible with cell viability and leads to the accumulation of SL RNA with a cap structure defective at positions +3 and +4.. Transsplicing utilization of the SL RNA is not detectably affected in mt57-/- cells, analysis of the SL cap structure in mt57-/- cells, overview |

silencing of TbMT48 mRNA by RNAi downregulation does not produce a lethal phenotype, as MT48-RNAi trypanosomes remain viable even after 10 days of tetracycline induction, generation of MT48 KO clonal cell lines by homologous recombination with PCR-generated cassettes. An observed defect in cap 4 modification, specific for MT48 ablation, can be complemented by reintroduction of a copy of the MT48 gene into mt48-/- cells |

the substitutions of residues S78, H86 and Q113 only mildly affect RNA binding and catalysis, so they are not essential for CMTr2 MTase activity |
