Abstract RNA isolated from BAI strain A (Myeloblastosis) Avian Tumor
Virus can be fractionated into two fractions on a sucrose density
gradient, one of higher molecular weight and one of low molecular
weight. The low molecular weight (LMW) virus RNA was found to
chromatograph the same as E. coli tRNA on a DEAE cellulose column
and to have elution properties similar to myeloblast tRNA on a MAK
column. A portion of the LMW virus RNA fraction was demonstrated
to have the ability to accept amino acids in an energy requiring,
aminoacyl-synthetase catalyzed reaction. The acceptance exhibited
toward nine amino acids tested individually varied considerably.
The pattern of amino acid acceptance shown with LMW virus RNA
did not correspond to that seen with myeloblast tRNA. Finally,
the LMW virus RNA fraction was shown to transfer accepted amino
acids to a growing peptide chain in a cell-free polysome system.
The LMW virus RNA fraction was, thus, characterized as transfer RNA. The presence of a transfer RNA possessing a modified pattern
of amino acid acceptance is of significance in terms of translational
control of protein synthesis.
