Influence of pH on the stability of some aminoacyl transfer ribonucleic acids and their elution pattern in chromatography on columns of methylated albumin adsorbed on kieselguhr

  • At pH 5.3 and 4.5 the half life of valyl-, threonyl-, leucyl- and seryl-tRNA from E. coli K 12 is significantly higher than at pH 6.8. While no changes were observed in the MAK elution patterns of valyl- and threonyl-tRNA, leucyl-tRNA was eluted in two peaks at pH 6.8 and 5.3 and in one broad peak at pH 4.5. Seryl-TRNA - two peaks at pH 6.8 - was separated in three peaks at pH 5.3 and 4.5. Rechromatography of these peaks at the other pH suggests the existence of at least four species of seryl-tRNA in E. coli K 12.
