Crosslinking studies of the bacterial RNase P holoenzyme and functional characterisation of the novel protein-only RNase P from Arabidopsis thaliana

Ribonuclease P (RNase P) is the ubiquitous processing enzyme that generates the mature 5'-termini of tRNA molecules. In Bacteria and Archaea the enzyme is a ribonucleoprotein, whereas in some Eukarya the RNAse P is exclusively proteinaceous. This work is focused on two topics: (i) crosslinking studies of bacterial RNase P holoenzyme utilizing novel 2’- ribooligonucleotides and (ii) functional investigations to the catalytical mechanism of recently discovered protein-only RNase P from Arabidopsis thaliana
