Glycosylated Swiss-model molecular dynamics trajectory of SARS-CoV-2 spike glycoprotein

posted on 08.05.2020, 18:30 by Oliver Grant, Robert Woods
Molecular dynamics simulation trajectory. The system is the SARS-CoV-2 spike glycoprotein with glycans modeled on using GLYCAM-Web. SARS-CoV2 spike (S) protein structure – A 3D structure of the prefusion form of the S protein (RefSeq: YP_009724390.1, UniProt: P0DTC2 SPIKE_SARS2), based on a Cryo-EM structure (PDB code 6VSB), was obtained from the SWISS-MODEL server (swissmodel.expasy.org). The model has 95% coverage (residues 27 to 1146) of the S protein.
The site specific glycans used to model a glycoform representative of the data obtained from the S glycoprotein expressed in HEK293 cells, are presented below: Hybrid: DManpα1-6[DManpα1-3]DManpα1-6[DGlcpNAcβ1-2DManpα1-3]DManpβ1-4DGlcpNAcβ1-4DGlcpNAcβ1-OH Glycosites: 657 FA2: DGlcpNAcβ1-2DManpα1-6[DGlcpNAcβ1-2DManpα1-3]DManpβ1-4DGlcpNAcβ1-4[LFucpα1-6]DGlcpNAcβ1-OH Glycosites: 149, 165, 331, 343, 616, 1134 A2: DGlcpNAcβ1-2DManpα1-6[DGlcpNAcβ1-2DManpα1-3]DManpβ1-4DGlcpNAcβ1-4DGlcpNAcβ1-OH Glycosites: 1098 FA2B: DGlcpNAcβ1-2DManpα1-6[DGlcpNAcβ1-4][DGlcpNAcβ1-2DManpα1-3]DManpβ1-4DGlcpNAcβ1-4[LFucpα1-6]DGlcpNAcβ1-OH Glycosites: 74, 282 M5: DManpα1-6[DManpα1-3]DManpα1-6[DManpα1-3]DManpβ1-4DGlcpNAcβ1-4DGlcpNAcβ1-OH Glycosites: 61, 122, 603, 709, 717, 801, 1074 M8: DManpα1-2DManpα1-6[DManpα1-2DManpα1-3]DManpα1-6[DManpα1-2DManpα1-3]DManpβ1-4DGlcpNAcβ1-4DGlcpNAcβ1-OH Glycosites: 234 Glycan naming system. In cases where the mass spectrometry data allows for multiple structures, such as FA2/FA1B, the glycan with the least ambiguity was selected. For example, FA2 was selected over FA1B, as the position of the single antennae is ambiguous.
