Publication Abstract from PubMed

Two synthetic O-GlcNAc-bearing peptides that elicit H-2Db-restricted glycopeptide-specific cytotoxic T cells (CTL) have been shown to display nonreciprocal patterns of cross-reactivity. Here, we present the crystal structures of the H-2Db glycopeptide complexes to 2.85 A resolution or better. In both cases, the glycan is solvent exposed and available for direct recognition by the T cell receptor (TCR). We have modeled the complex formed between the MHC-glycopeptide complexes and their respective TCRs, showing that a single saccharide residue can be accommodated in the standard TCR-MHC geometry. The models also reveal a possible molecular basis for the observed cross-reactivity patterns of the CTL clones, which appear to be influenced by the length of the CDR3 loop and the nature of the immunizing ligand.

Crystal structures of two H-2Db/glycopeptide complexes suggest a molecular basis for CTL cross-reactivity.,Glithero A, Tormo J, Haurum JS, Arsequell G, Valencia G, Edwards J, Springer S, Townsend A, Pao YL, Wormald M, Dwek RA, Jones EY, Elliott T Immunity. 1999 Jan;10(1):63-74. PMID:10023771^[1]

[[https://www.uniprot.org/uniprot/NCAP_SENDZ NCAP_SENDZ]] Encapsidates the genome in a ratio of one N per six ribonucleotides, protecting it from nucleases. The nucleocapsid (NC) has a helical structure with 13.07 N per turn. The encapsidated genomic RNA is termed the NC and serves as template for transcription and replication. Replication is dependent on intracellular concentration of newly synthesized N, termed N(0), which corresponds to the protein not associated with RNA. In contrast, when associated with RNA, it is termed N. During replication, encapsidation by N(0) is coupled to RNA synthesis and all replicative products are resistant to nucleases.
