There is a little discrepancy here,  likely due to the dearth of protein modeling for the complete protein of surfactant protein D.  In any case, you can see from the picture of Arroyo et al, (top) and a diagram (middle from a commonly reproduced diagram available on the internet) which has N glycosylation site in a different relative position, and Arroyo’s diagram again lower middle which might come close but is not exactly where the bright spot is on the AMF image, and the bottom image, also from a google search which doesn’t bother to show an N glycosylation site.  Dotted line lines up where this “might” be in parallel diagrams. You can see there is lots of variation.  So to be more precise in this i should have overlapped the N terminals in the second figure down.  and checked to see if in fact the branch indicated actually was intended to be a glycosylation site. (not so LOL). I will try to edit this later.
