  • Title: Amino acid composition and proteolytic generated domains of higher plant tubulin.
    Author: Picquot P, Vantard M, Amiri I, Fausser L, Lambert AM.
    Journal: Biochem Biophys Res Commun; 1988 Oct 14; 156(1):304-11. PubMed ID: 3178836.
    Abstract:
    The molecular architecture of tubulin from higher plant remains unknown. In this report we have made an attempt to identify higher plant tubulin domains using total and limited proteolysis of Haemanthus endosperm tubulin. The tubulin was previously purified and characterized (Picquot and Lambert 1988). The amino acid composition revealed a high content of basic residues, such as arginine and lysine. Tubulin domains were probed by tryptic and chymotryptic cleavage and analyzed by immunoblotting using specific monoclonal antibodies against alpha or beta subunits. These data shed light on specific properties of the higher plant tubulin.
