Transition from vegetative cells to aerial mycelium and spores of Streptomyces collinus is accompanied by changes in the pattern of proteins phosphorylated. Preparation from spores exhibits lower phosphorylation activity than those of vegetative cells and aerial mycelium. Phosphorylation of proteins from aerial mycelium was markedly stimulated by the presence of Mn 2+ . Our data indicate that phosphorylation of proteins on Ser/Thr residues is involved in transition of vegetative cells to aerial mycelium.
