Amino acid coding in Sarcina lutea and Saccharomyces cerevisiae.

Aminoacyl-tRNA's from Sarcina lutea were tested for incorporation into protein in a heterologous system from Escherichia coli or for biniding in a homologous system from Sarcina lutea. Aminoacyl-tRNA's from Saccharomyces cerevisiae were tested for biniding in a homologous Saccharomyces cerevisiae system. Synthetic polyribonucleotides were used as messengers. The code which exists in Sarcina lutea and Saccharomyces cerevisiae is the same as in Escherichia coli.
