construction of chimera between Cfr and RlmN from Echerichia coli to analyze C2/C8 and C2 methylation specificity, respectively. The catalytic site is expected to be responsible for the C2/C8 specificity. Almost all replacements show no function in the primer extension assay, apart from a few that have a weak effect |
