Derivatives of the yeast mitochondrial ribosomal protein MrpS28 replace ribosomal protein S15 as functional components of the Escherichia coli ribosome.

Abstract excerpt

The mitochondrial ribosomal protein MrpS28 is considerably larger than its eubacterial homolog, Escherichia coli ribosomal protein S15 (Eco S15). Relative to a region of homology that spans the entire length of the bacterial protein, mature MrpS28 is extended by 117 and 48 amino acids at its amino and carboxyl termini, respectively. Both the amino-terminal and S15-like domains of MrpS28 are essential for function...
