(A) Build away from ABO and you may H antigens on the human red tissues. H antigen designed of the action of FUT1 towards oligosaccharide forerunner chains where in actuality the critical D-galactose residue is related in order to carbon dioxide cuatro of one’s penultimate N-acetyl D-glucosamine deposit (sorts of II strings). (B) Design off Le blood group antigens inside physical secretions. Secretor gene (FUT2) handles the manufacture of H antigen, that’s converted to A beneficial otherwise B antigen if the relevant active ABO glycosyltransferase is available.
The brand new ABH, Ce b -productive structures was designed to the oligosaccharide predecessor stores in which the critical D-galactose deposit is related so you’re able to carbon step three of penultimate N-acetyl D-glucosamine residue (variety of I chain) If the FUT dos is deficient the brand new Le an excellent effective framework predominates
The term from ABH antigens within the buildings and the entire body liquids other than bloodstream structure is controlled by the secretor gene (FUT2), and that encodes a leader step 1,2-fucosyltransferase effective at animated L-fucose to carbon 2 off galactose (beta, 1-3) N-acetyl D-glucosamine–which includes glycans.
