tubulin-tyrosine ligase [Schizosaccharomyces pombe]
Protein Classification
tubulin--tyrosine ligase family protein( domain architecture ID 10504173)
tubulin--tyrosine ligase (TTL) family protein such as TTL that catalyzes the post-translational retyrosination of detyrosinated a-tubulin, and TTL-like (TTLL) enzymes that catalyze the glycylation and/or glutamylation, the post-translational addition of glycines and glutamates to genetically encoded glutamates in the intrinsically disordered tubulin C-terminal tails

Tubulin-tyrosine ligase family; Tubulins and microtubules are subjected to several post-translational modifications of which the reversible detyrosination/tyrosination of the carboxy-terminal end of most alpha-tubulins has been extensively analysed. This modification cycle involves a specific carboxypeptidase and the activity of the tubulin-tyrosine ligase (TTL). The true physiological function of TTL has so far not been established. Tubulin-tyrosine ligase (TTL) catalyzes the ATP-dependent post-translational addition of a tyrosine to the carboxy terminal end of detyrosinated alpha-tubulin. In normally cycling cells, the tyrosinated form of tubulin predominates. However, in breast cancer cells, the detyrosinated form frequently predominates, with a correlation to tumour aggressiveness. On the other hand, 3-nitrotyrosine has been shown to be incorporated, by TTL, into the carboxy terminal end of detyrosinated alpha-tubulin. This reaction is not reversible by the carboxypeptidase enzyme. Cells cultured in 3-nitrotyrosine rich medium showed evidence of altered microtubule structure and function, including altered cell morphology, epithelial barrier dysfunction, and apoptosis. Bacterial homologs of TTL are predicted to form peptide tags. Some of these are fused to a 2-oxoglutarate Fe(II)-dependent dioxygenase domain. : Pssm-ID: 397308 Cd Length: 291 Bit Score: 234.15 E-value: 1.19e-74
