Disease relevance of SCO1321


High impact information on SCO1321

  • Analysis of the tuf gene organization in nine producers of kirromycin-type antibiotics revealed that they all contain homologues of tuf1 and sometimes of tuf3 but that tuf2 was found in S. ramocissimus only [2].
  • Besides the tuf1 gene encoding the regular elongation factor EF-Tu1 a gene similar to S. coelicolor tuf3 for a specialized EF-Tu was located in the P. rosea genome [3].
  • The transcription start site of tuf3 was located approximately 195 nt upstream of the translation start site [1].
  • Replacement of the 5'-half of tuf3 by an antibiotic resistance cassette had no detectable effect on phenotype, indicating that tuf3 is not essential for growth or differentiation [1].
  • However, tuf3 transcription was observed in cultures of S. coelicolor M145 shortly after nutritional shiftdown (which resulted in the disappearance of tuf1 transcripts) and after addition of serine hydroxamate, both of which induce the stringent response [1].

Associations of SCO1321 with chemical compounds

  • Transcription of tuf3 was also observed in transition-phase and stationary-phase cultures of S. coelicolor J1681, a strain deleted for bldA (which specifies a tRNA(Leu) for the rare leucine codon UUA) [1].
