Abstract

This assignment of codons in Halobacterium cutirubrum for some of the acidic and basic amino acids was undertaken. Although trinucleotides could not be used successfully in the halophile ribosomal binding system, the unfractionated aminoacyl-tRNAs responded to the established codons in the heterologous binding system using E. coli ribosomes. This suggested that H. cutirubrum uses the established code in full.

Two species of lysine accepting tRNA were purified. Their coding response to Poly(A) and Poly(A,G) was studied. tRNA[Lys,1] recognized both AAA and AAG codons while tRNA[Lys,2] recognized AAA preferentially in both the homologous and heterologous ribosomal binding systems.
