evidence for a functional alpha-tubulin cycle involving an inherent carboxypeptidase and a recharging ligase was apparent in 3t3 cells from the preponderance of glu-rich mts induced by taxol treatment or the micro-injection of certain antibodies either protecting the detyrosinated form ( glu-tubulin antibodies ) or inhibiting retyrosination ( ligase antibodies ) .
