Other name(s): |
dephospho-CoA pyrophosphorylase; pantetheine phosphate adenylyltransferase; dephospho-coenzyme A pyrophosphorylase; 3′-dephospho-CoA pyrophosphorylase |
Systematic name: |
ATP:pantetheine-4′-phosphate adenylyltransferase |
Comments: |
The enzyme from several bacteria (e.g. Escherichia coli, Bacillus subtilis and Haemophilus influenzae) has been shown to be bifunctional and also to possess the activity of EC 2.3.1.157, glucosamine-1-phosphate N-acetyltransferase. |
