Summary

Automatic Translation

Her beskriver vi en metode for rensing histidin-merket pyrophosphokinase enzymer og utnytte tynt lag kromatografi radiolabelled underlag og produkter til analysen for den enzymatiske aktiviteten i vitro. Enzym aktivitet analysen er bredt aktuelt noen kinase, nucleotide cyclase eller fosfor-transfer reaksjon som mekanisme inkluderer nukleotid trifosfat hydrolyse.
