Preliminary Characterization of a Guanosine 3′,5′-Polyphosphate [(p)ppGpp] Synthesizing Enzyme from Thermus thermophilus JF Microbiology, VO 123 IS 2 SP 383 OP 386 DO https://doi.org/10.1099/00221287-123-2-383 PB Microbiology Society, SN 1465-2080, AB A guanosine 3′,5′-bis(diphosphate) (ppGpp) and guanosine 3′-diphosphate 5′-triphosphate (pppGpp) synthesizing enzyme is present in the ribosomal fraction of Thermus thermophilus. The enzyme is comparable to the Escherichia coli (p)ppGpp synthetase I (stringent factor) in that it requires ribosomes, mRNA and codon-specific, uncharged tRNA. The ribosomal complex can be replaced by methanol. Ribosomes from Escherichia coli do not function as effectors of the Thermus thermophilus enzyme., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-123-2-383
