Peak 5 of the trimers of surfactant protein D is shown this post. The peak number is counted with the N termini junction peak as peak 1 and moving in a mirrored direction from that point toward the CRD peak.  Peak 1 (N termini junction, well described, obvious and tallest); tiny peak (peak 2, not currently described, small, and between peak 1 and the alledged glycosylation peak); peak 3, the described glycosylation peak; peak 4 (lateral to the glycosylation peak, detected very frequently, large, and not as tall as the glycosylation peak); Peak 5, below, is not tall, and quite thin, but detected frequently enough to make it a likely event.
