Disease relevance of ECM31

 

High impact information on ECM31

  • Furthermore, yeast genes ECM31 and YIL145c, which both have structural homology to genes of the bacterial pantothenic acid pathway, were also required for pantothenic acid biosynthesis [2].
  • KPHMT enzyme activity could be measured in purified mitochondria from both pea leaves and Arabidopsis suspension cultures [3].
  • Two genes encoding KPHMT and one for PtS were identified in the Arabidopsis thaliana genome, and cDNAs for all three genes were amplified by PCR [3].
  • DNA sequence analysis revealed that the DNA fragment encodes ECM31, the deletion of which had previously been identified as a calcofluor white-sensitive mutation [1].
  • 7 haploid and the ecm31 disruptant required pantothenic acid at 35 degrees C for its growth, suggesting that Kyokai no [1].
