Posttranslational modifications of α-tubulin of Toxoplasma gondii

Abstract

The posttranslational modifications of α-tubulin of Toxoplasma gondii were characterized by antibodies and biochemical analysis of the carboxy-terminal peptide. α-Tubulin is acetylated and glutamylated. Side chains with up to three glutamate residues are linked to Glu445 of T. gondii α-tubulin. The data suggest that the site of glutamylation on α-tubulin is conserved over a broad range of species. © Springer-Verlag 2004.
