Extended Data Fig. 8 ∣. Microtubules missing their β-tubulin tails are poor substrates for TTLL6.
a,b. LC-MS spectra of intact wild-type microtubules at times 0 h (a) and 2 h (b) after incubation with TTLL6. Tubulin isotypes and glutamate numbers are indicated on top. c,d. LC-MS spectra of αβΔ-tail microtubules at times 0 h (c) and 2 h (d) after incubation with TTLL6 (Methods). Spectra labeled as in a.
