(A) Framework from ABO and H antigens toward human purple tissue. H antigen designed from the action out-of FUT1 towards the oligosaccharide precursor organizations where in actuality the critical D-galactose residue is related so you can carbon dioxide cuatro of the penultimate Letter-acetyl D-glucosamine deposit (type of II strings). (B) Framework off Le blood classification antigens into the bodily secretions. Secretor gene (FUT2) regulates the production of H antigen, which will be transformed into An excellent otherwise B antigen if for example the involved productive ABO glycosyltransferase can be obtained.
The fresh ABH, Ce b -productive formations is molded on oligosaccharide predecessor organizations where in fact the terminal D-galactose deposit is linked to carbon dioxide step three of your own penultimate N-acetyl D-glucosamine residue (particular I strings) If the FUT 2 is actually lacking the Le a good effective structure predominates
The word regarding ABH antigens in the tissues and the body fluids other than simply blood cells is controlled of the secretor gene (FUT2), which encodes a leader step 1,2-fucosyltransferase effective at move L-fucose in order to carbon 2 out of galactose (beta, 1-3) N-acetyl D-glucosamine–which has had glycans.
