polyglycylation

Polyglycylation is a form of posttranslational modification of glutamate residues of the carboxyl-terminal region tubulin in certain microtubules (e.g., axonemal) originally discovered in Paramecium,{{cite journal |vauthors=Redeker V, Levilliers N, Schmitter JM, Le Caer JP, Rossier J, Adoutte A, Bré MH |title=Polyglycylation of tubulin: a posttranslational modification in axonemal microtubules |journal=Science |volume=266 |issue=5191 |pages=1688–1691 |year=1994 |pmid=7992051 |doi=10.1126/science.7992051|bibcode=1994Sci...266.1688R }} and later shown in mammalian neurons as well.{{cite journal |author=Banerjee Asok |title=Coordination of posttranslational modifications of bovine brain alpha-tubulin.
