Archaeal CCA-adding enzyme builds and repairs the 3'-end of tRNA [1-4]. This is the C-terminal domain (tail) of CCA-adding enzyme, which serves as a ruler to ensure that only tRNAs and tRNA-like transcripts are substrates for the enzyme and also contributes to the discrimination between stable and unstable RNA substrates [4].
Members of this family belong to a large family of nucleotidyltransferases [1]. This family includes kanamycin nucleotidyltransferase (KNTase) which is a plasmid-coded enzyme responsible for some types of bacterial resistance to aminoglycosides. KNTa ...
Members of this family belong to a large family of nucleotidyltransferases [1]. This family includes kanamycin nucleotidyltransferase (KNTase) which is a plasmid-coded enzyme responsible for some types of bacterial resistance to aminoglycosides. KNTase in-activates antibiotics by catalysing the addition of a nucleotidyl group onto the drug.
Members of this family adopt a structure consisting of a five helical bundle core. They are predominantly found in Archaeal tRNA nucleotidyltransferase, following the catalytic nucleotidyltransferase domain [1].
