2.4.1.69 type 1 galactoside alpha-(1,2)-fucosyltransferaseIUBMB Comments
The enzyme acts on a glycoconjugates where R (see reaction) is a glycoprotein or glycosphingolipid. The recognized moiety of the substrate is known as a type 1 histo-blood group antigen precursor disaccharide, and the action of the enzyme produces an H type 1 antigen. In humans the main enzyme performing this reaction is encoded by the FUT2 gene (also known as the Secretor gene), which is also able to act on type 2 substrates (see EC 2.4.1.344). The enzyme from the bacterium Helicobacter pylori cannot act on type 2 substrates.

acceptor specificity, overview. C6-sulfation of terminal Gal in the LacNAc unit increases acceptor efficiency, C-6 sialylation abolishes acceptor ability, C6-sulfation of GlcNAc in LacNAc type 2 decreases by 80% the acceptor ability, whereas LacNAc type 1 is unaffected, the C-4 hydroxyl rather than the C-6 hydroxyl group of the GlcNAc moiety in LacNAc type 1 is essential for activity, the acrylamide copolymer of Galbeta(1-3)GlcNAcbeta-O-Al is the best acceptor among the acrylamide copolymers, Lewis x does not serve as an acceptor

gut colonization by symbiotic bacteria stimulates ERK and JNK signal transduction pathways, resulting in activation of transcription factors ATF2 and c-Jun, respectively. This increases transcription of fut2 mRNA and expression of alpha1,2/3-fucosyltransferase activity, resulting in a highly fucosylated intestinal mucosa characteristic of the adult mammalian gut. Blocking the ERK and JNK signaling cascade inhibits the ability of colonization to induce elevated fut2 mRNA and fucosyltransferase activity in the mature colon

To demonstrate that the variable regions determine substrate specificity and to investigate which of the variable regions of R1,2-FucT is responsible, six chimeric R1,2-FucTs are constructed by domain swapping between Escherichia coli FucTs WbsJ and WbwK. Three chimeras are inactive, the other three chimeras have greater substrate spectra than FucT WbwK but lower activity than WbsJ.

bp428 G>A is a spontaneous nonsense mutation, 739G > A substitution does not inactivate the enzyme
additional information
the spontaneous G428A nonsense mutation in FUT2 provides not absolute protection against symptomatic GII.4 Norovirus infection: during a norovirus outbreak in an elderly nursing home only 1 of 17 nonsecretors was infected, whereas 70% of the secretors were infected
additional information
recombinant full length enzyme has a specific activity over 80fold higher than the truncated enzyme missing the first 27 amino acid residues from the N-terminus, comprising the cytoplasmic and transmembrane domains. The native and the recombinant full-length enzyme display significant activity in absence of detergent or phospholipid and are optimally activated in presence of Triton CF-54 detergent. The truncated enzyme is optimally activated by CHAPSO, showing littel activity in absence
