KEGG   ENZYME: 6.3.2.25Help
Entry
EC 6.3.2.25                 Enzyme                                 

Name
tubulin---tyrosine ligase
Class
Ligases;
Forming carbon-nitrogen bonds;
Acid-D-amino-acid ligases (peptide synthases)
BRITE hierarchy
Sysname
alpha-tubulin:L-tyrosine ligase (ADP-forming)
Reaction(IUBMB)
ATP + detyrosinated alpha-tubulin + L-tyrosine = alpha-tubulin + ADP + phosphate [RN:R04730]
Reaction(KEGG)
Substrate
ATP [CPD:C00002];
detyrosinated alpha-tubulin [CPD:C05234];
L-tyrosine [CPD:C00082]
Product
alpha-tubulin [CPD:C01392];
ADP [CPD:C00008];
phosphate [CPD:C00009]
Comment
L-Tyrosine is linked via a peptide bond to the C-terminus of de-tyrosinated alpha-tubulin (des-Tyromega-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.
