  • Title: Template-independent synthesis of guanosine tetra- and pentaphosphates on ribosomes.
    Author: Belitsina NV, Klyachko EV, Shakulov RS.
    Journal: FEBS Lett; 1983 Oct 03; 162(1):39-42. PubMed ID: 6352335.
    Abstract:
    It is shown that Escherichia coli ribosomes carrying poly(Lys)-tRNA can form (p)ppGpp in the presence of stringent factor in the absence of the poly(A) template. Template-independent synthesis of (p)ppGpp is suppressed by tetracycline and partially decreases if deacylated tRNA is omitted.
