The cDNA cloning of a pea (<i>Pisum sativum</i>) seed lipoxygenase. Sequence comparisons of the two major pea seed lipoxygenase isoforms

Abstract

Cloning and sequencing of two cDNAs from mRNA of maturing pea (Pisum sativum) seeds allowed the deduction of the complete amino acid sequence of a lipoxygenase polypeptide which is most similar to that of soya-bean lipoxygenase 2. The predicted Mr of this polypeptide is 97134, and its sequence permits comparisons between the lox2-type and the lox3-type lipoxygenase isoforms from pea and soya bean (Glycine max).
