Definition of bifunctional in US English:



  • 1Having two functions.

    • ‘Whether the functionally independent mutants are the result of mutations in a single bifunctional gene or two separate genes has not been determined.’
    • ‘Consequently, these results demonstrate that CS and MeIQx have a bifunctional action, with similar induction patterns of specific CYP proteins, mutagenic activity and UDPGT activity.’
    • ‘To the best of our knowledge, there are no previous reports of this type of bifunctional photoactivator.’
    • ‘In maize endosperm the pullulanase-type DBE activity is thought to have a bifunctional role, assisting in both starch synthesis and degradation.’
    • ‘Rather, the genetic and biochemical analyses suggest that Sun is a bifunctional protein.’
  • 2Chemistry
    Having two highly reactive binding sites in each molecule.

    ‘bifunctional enzymes retain stable levels of activity’
    • ‘Epoxy compounds are highly reactive bifunctional alkylating agents, which may attack and bind covalently to DNA and cause mutagenic events.’
    • ‘These results suggest that hexokinase is a bifunctional enzyme with catalytic and sugar-sensing activities in plants.’
    • ‘It has been suggested that bifunctional molecules like alcohol can penetrate into the hydrophobic core of lys modifying its structural and dynamic properties.’
    • ‘The interconversion of the bifunctional enzyme is catalyzed by cAMP-dependent protein kinase, which in turn is regulated by circulating peptide hormones.’
    • ‘The presence of bifunctional chitinase/chitosanase enzymes were only observed in the mycorrhizal part of the root system, showing the localized character of the induction.’
