Transferase Transferase
Type A Transferase Type B
Type O
That all makes sense, but I still don’t quite understand what’s going on with people
with Type O blood. Why don’t they get monosaccharides on the end of their sugar
chains? Seems unfair!
Type O people also have the genes associated with glycosyltransferases, but since
there is no enzyme activity for the proteins created by those genes, no saccharide is
attached at the tips. The activity may have been lost because of a genetic mutation
during the evolutionary process.
A mutation? Cool!
So to wrap it all up: The ABO blood group system is nothing but the result of
differences in glycosyltransferase genes.
Nemoto, you must have a genetic mutation that gives you an oversized brain. How
else could you possibly know so much?!
Gyuh...
