Chloroplast and Cytoplasmic Enzymes: VIII. Amino Acid Composition of the Pea Leaf Aldolases.
Pea leaf chloroplast aldolase contains seven more aspartyl (asx) residues and four fewer leucine and isoleucine residues than the cytoplasmic enzyme. The two forms are therefore primary isoenzymes, differing in amino acid sequence.
