Effects of terminal deletions in C5 protein on promoting RNase P catalysis.

Abstract excerpt

Deletion derivatives of C5 protein, the protein cofactor of Escherichia coli RNase P, were constructed as soluble MBP (maltose-binding protein) fusion proteins to assess the deletion effects on promoting RNase P catalysis and on binding to M1 RNA, the catalytic subunit of the enzyme. The C5 protein, with large terminal deletions, retained its promoting activity of RNase P catalysis under protein excess conditions...
