We report the characterization and partial purification of potato mitochondrial RNase Z, an endonuclease that generates mature tRNA 3' ends. The enzyme consists of one (or more) protein(s) without RNA subunits. Products of the processing reaction are tRNA molecules with 3' terminal hydroxyl groups and 3' trailers with 5' terminal phosphates. The main processing sites are located immediately 3' to the discriminator and one nucleotide further downstream. This endonucleolytic processing at and clos ...[more]
