Other name(s): |
PduX |
Systematic name: |
ATP:L-threonine O3-phosphotransferase |
Comments: |
The enzyme is involved in the de novo synthesis of adenosylcobalamin. It is specific for ATP and free L-threonine. In the bacterium Salmonella enterica the activity with CTP, GTP, or UTP is 6, 11, and 3% of the activity with ATP. |
