Enzyme Information
| 6.3.2.25 |
Tubulin--tyrosine ligase.
based on mapping to UniProt P38584
ATP + detyrosinated alpha-tubulin + L-tyrosine = alpha-tubulin + ADP + phosphate.
-!- L-tyrosine is linked via a peptide bond to the C-terminus of de-tyrosinated alpha-tubulin (des-Tyr(omega)-alpha-tubulin). -!- The enzyme is highly specific for alpha-tubulin and moderately specific for ATP and L-tyrosine. -!- L-phenylalanine and 3,4-dihydroxy-L-phenylalanine are transferred but with higher Km values.
