Abstract
Growth-associated histone kinases have been extracted from Physarum polycephalum nuclei and resolved into two components by ion-exchange chromatography. The two component activities have different substrate specificities and different times of appearance in the cell cycle. It is proposed that the enzyme(s) phosphorylate H1 histone in vivo in G2 phase, possibly sequentially in time at different sites in the H1 amino acid sequence.This publication has 20 references indexed in Scilit:
