Alpha3-fucosyltransferases (alpha3-FucTs) are key enzymes in creating essential glycoconjugates. This review details their substrate specificity and presents a molecular fold prediction for these important enzymes.

Area of Science:

  • Biochemistry
  • Glycobiology
  • Enzymology

Background:

  • Alpha3-fucosyltransferases (alpha3-FucTs) are crucial enzymes.
  • They catalyze the final step in synthesizing glycoconjugates vital for cell adhesion and lymphocyte recirculation.
  • Six human alpha3-FucT family members exhibit highly regulated expression patterns.

Purpose of the Study:

  • To review current knowledge on alpha3-FucT substrate specificity.
  • To explore amino acid contributions to differential acceptor binding and GDP-fucose interaction.
  • To present a molecular fold prediction for alpha3-FucTs.

Main Methods:

  • Analysis of existing study results on FucT sequences.
  • Investigation of amino acid roles in substrate binding.
