Subunit structurei

Homodimer in solution. Component of RNase P which consists of a catalytic RNA component and at least 5 protein subunits. Forms a heterotetrameric subcomplex with Rnp3. Reconstituted enzyme missing individual protein subunits is suboptimally active, showing each subunit contributes to optimization of activity.4 Publications
