    Phenotypes of a mutant

  • growth defect in the presence of gamma-aminobutyrate [Pubmed|24127574]
  • no growth with gamma-aminobutyrate as single carbon source [Pubmed|24529384]

    • The protein

    Catalyzed reaction/ biological activity

  • 4-aminobutanoate + 2-oxoglutarate = succinate semialdehyde + L-glutamate (according to Swiss-Prot)
  • the protein was reported to be involved in norspermidine production and biofilm disassembly [Pubmed|22541437]; however, this is not the case [Pubmed|24529384]and the original paper has been [http://www.cell.com/cell/fulltext/S0092-8674(15)00495-X retracted]
