Studies on Fraction I Protein

Abstract

<p> Studies on the isolation and purification of Fraction I protein from various plants are described. Clear differences in the electrophoretic mobilities of Fr I from various species were observed. The genetic implication of observations on the electrophoretic mobilities of Fr I from wheat, rye and triticales are discussed. It is suggested that a non-chromosomal gene codes for Fr I. Conclusions are drawn from the fingerprint, N-terminal amino acid, and amino acid analysis studies. The presence of ribulose diphosphate carboxylase activity in Fr I protein is also investigated.</p>
