EC Tree
IUBMB Comments Has a wide specificity. In the reverse direction, N-phosphoglycine and N-phosphohistidine can also act as phosphate donors, and ADP, dADP, GDP, CDP, dTDP, dCDP, IDP and UDP can act as phosphate acceptors (in decreasing order of activity).
The expected taxonomic range for this enzyme is: Saccharomyces cerevisiae
