Disease relevance of asnA

 

High impact information on asnA

 

Biological context of asnA

  • The stimulating effect of AsnC on asnA transcription is abolished by asparagine, while the autoregulation of asnC is not affected by asparagine [7].
  • As regards nontransgenic L. corniculatus plants, in one location flow of asnA transgene was detected up to 18 m from the 1.8 m2 donor plot [8].
  • Taken with known sequences for asnA and phoS this completes the sequence of a segment of about 17 kilobases or 0.4 min of the E. coli genome [9].
 

Associations of asnA with chemical compounds

  • The asnB gene is located near gal.AsnA+ asnB and asnA asnB+ strains were constructed, and the asparagine synthetic reaction was characterized in extracts [10].
