Disease relevance of guaA


High impact information on guaA

  • PCR-mediated deletion mutagenesis and cloning identified a 120-bp fragment upstream from the guaA gene to be the actual regulator [2].
  • Primer extension analysis mapped the transcription start site to be the first 'G' residue of the translation start codon GTG of the guaA gene [2].
