Structural basis of RNA processing by human mitochondrial RNase P

WebThe chemical structure of RNA is very similar to that of DNA, but differs in three primary ways: . Unlike double-stranded DNA, RNA is usually a single-stranded molecule (ssRNA) in many of its biological roles and consists of much shorter chains of nucleotides. However, double-stranded RNA (dsRNA) can form and (moreover) a single RNA molecule can, by … WebThe hammerhead ribozyme has been thought of as a ‘‘prototype’’ ribozyme in the same sense that lysozyme and serine proteases have been thought of as ‘‘prototype’’ conventional protein enzymes, and for that reason the hammer-head ribozyme has attracted intense experimental scrutiny.

Ribonuclease P (EC 3.1.26.5, RNase P) is a type of ribonuclease which cleaves RNA. RNase P is unique from other RNases in that it is a ribozyme – a ribonucleic acid that acts as a catalyst in the same way that a protein-based enzyme would. Its function is to cleave off an extra, or precursor, sequence of RNA on tRNA molecules. Further, RNase P is one of two known multiple turnove… WebIn contrast to nuclear or bacterial RNase P, mtRNase P is not a ribozyme but comprises three protein subunits that carry out RNA cleavage and methylation by unknown …
