Various soluble glycosyltransferases are found in serum, colostrum,
I am curious to find out what the consensus of opinion is as to what the
function(s), if indeed there are any, of these forms of the
glycosyltransferases might be.
For example, is transferase activity impossible due to the scarcity of
nucleotide-sugar substrates? Can they still bind to target
oligosaccharide sequences, without transferase activity, in a lectin
like manner? or are they simply unwanted secreted cellular products?
Any thoughts out there?
