Verosuggested: NoneSoftware and Algorithms Sentences Resources Detection and relative quantification of the prevalence of individual glycans was accomplished using the total ion mapping (TIM) and neutral loss scan (NL scan) functionality of the Xcalibur software package version 2.0 (Thermo Fisher Scientific) as previously described (38,39). Xcalibursuggested: (Thermo Xcalibur, RRID:SCR_014593)Proteome Discoverer 1.4) with mass tolerance set as 20 ppm for precursors and 0.5 Da for fragments. Proteome Discoverersuggested: (Proteome Discoverer, RRID:SCR_014477)The search output was filtered using ProteoIQ (v2.7) to reach a 1% false discovery rate at protein level and 10% at peptide level. ProteoIQsuggested: (PremierBiosoft Proteo IQ Software, RRID:SCR_018072)The S protein sequences from all of those genomes were aligned using EMBOSS needle v6.6.0 (61) via the EMBL-EBI provided web service (69). EMBOSSsuggested: (EMBOSS, RRID:SCR_008493)For further sequence analysis of SARS-CoV-2 S variants, the genomes of SARS-CoV-2 were downloaded from NCBI and GISAID and further processed using Biopython 1.76 to extract all sequences annotated as “surface glycoprotein” and to remove any incomplete sequence as well as any sequence containing unassigned amino acids. Biopythonsuggested: (Biopython, RRID:SCR_007173)For sequence analysis of human ACE2 variants, the single nucleotide polymorphisms (SNPs) of ACE2 were extracted from the NCBI dbSNP database and filtered for missense mutation entries with a reported minor allele frequency. dbSNPsuggested: (dbSNP, RRID:SCR_002338)Results from OddPub: We did not detect open data. We also did not detect open code. Researchers are encouraged to share open data when possible (see Nature blog).
