    The RNA components of Ribonuclease P (RNase P) are the catalytic subunits. This review discusses their properties, structure, and proposed mechanisms of action.

    Area of Science:

    • Biochemistry
    • Molecular Biology
    • Enzymology

    Context:

    • Ribonuclease P (RNase P) is a crucial enzyme involved in tRNA processing.
    • Historically, protein components were considered primary for RNase P activity.
    • Recent data highlights the catalytic role of RNA within RNase P.

    Purpose:

    • To review and synthesize existing data on the RNA components of RNase P.
    • To discuss the biochemical properties and structural characteristics of these RNA subunits.
    • To explore the proposed mechanisms underlying the catalytic action of RNase P RNA.

    Summary:

    • Evidence strongly indicates that the RNA moiety of RNase P functions as the catalytic subunit.
    • The review details the physicochemical properties of these polyribonucleotides.
