Disease relevance of nucA


High impact information on nucA

  • Immediately downstream from the nucA gene, in the complementary strand, we have identified an open reading frame composed of 135 codons, that we have named nuiA, whose expression in E. coli conferred heat-resistant NucA-inhibitory activity to cell-free extracts [2].
  • The 410-kb alpha megaplasmid of the heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120 was found to bear the nucA gene that encodes a sugar-nonspecific nuclease [3].

Anatomical context of nucA

  • With all constructs, tandem expression of nucA and nuiA results in aggregation and inclusion body formation of NucA, independent of the order of the genes, the relative expression of the two proteins and the temperature applied during expression [4].
