Introduction:The three dimensional crystal structure of hCG has been publish by Wu et al., Lapth et al., and Lustbader et al. The problem is that the crystal is missing 50%of the hCG molecular weight. It is missing the 4 N-linked and the 4 O-linked oligosaccharides andβ-subunit amino acid residues 113-145. Here we add back in these missing structures, and considering 11 reported consequences we predict the final structure of hCG, hyperglycosylated hCG, nicked hCG and hCG free β-subunit. Methods:The consequences of 11 report are considered. The missing structures are examined by 2 webware programs, Bioinformatics Toolkit (Max Planck Institute), and Bioinformatics and Computational Biology (IIT Delhi). Results&Discussion:Structures are proposed for hCG, hyperglycosylated hCG, nicked hCG and hCG freeβ-subunit, considering the charge effect that the 12 or 19 sialic acid residues may have, movement ofα-subunit loop 2 and movement of β-subunit safety belt.: Nicking causes a major structural change toβ-subunit loop 2.
