Biochem/physiol Actions
Transfers one phosphate from many nucleoside triphosphates to many nucleoside diphosphates. No activity when UMP is substituted for the diphosphate.
Reconstitution
Reconstitute with deionized water. Solution is believed to be stable for over 1 year while frozen.
Unit Definition
One unit will convert 1.0 μmole each of TDP and ATP to TTP and ADP per min at pH 7.6 at 25 °C in a coupled system with PK/LDH.
Physical form
Lyophilized, essentially sulfate-free powder. Contains sodium citrate with a trace of magnesium and EDTA salts.
