T599 0-121 Sentence denotes For glycan interaction, HCoV-NL63 and MHV utilize heparan sulfate proteoglycans (HSPGs) as attachment enhancers [87,124].
T600 122-170 Sentence denotes Viruses recognize HSPGs as attachment molecules.
T601 171-245 Sentence denotes In the spike (S) protein-deficient virions, the M protein recognizes HSPG.
T602 246-307 Sentence denotes The S proteins generally bind to the viral cellular receptor.
T603 308-396 Sentence denotes However, the M protein also acts as a receptor in the early step of HCoV-NL63 infection.
T604 397-473 Sentence denotes The M membrane protein of HCoV-NL63 recognizes the attachment site of HSPGs.
T605 474-650 Sentence denotes HCoV-NL63 M protein binds to HSPG for the initial attachment of virus to host cells and thereafter, the M and S proteins cooperate for virus entrance into the host cells [125].
T606 651-759 Sentence denotes HSPGs are glycosaminoglycan (GAG)-carrying proteins frequently used as a secondary receptor for viral entry.
T607 760-822 Sentence denotes HSPGs are composed of covalent-bonded HS chains as a GAG form.
T608 823-926 Sentence denotes The HS GAG linkage structure of tetrasaccharide exhibits GluAβ1,3GlcNAcα1,4Galβ1,3Galβ1,4Xylβ-O-serine.
T609 927-1113 Sentence denotes Glycosyltransferases involved in HS GAG synthesis include GlcAT-II (glucuronosyltransferase) and GlcNAcT-II (N-acetylglucosaminyltransferase II) for heparan sulfate synthesis (Figure 9).
T610 1114-1192 Sentence denotes GAG is used as docking sites for virus interaction with the host cell surface.
T611 1193-1256 Sentence denotes GAGs contain negatively charged N- and O-sulfated sugars [126].
T612 1257-1448 Sentence denotes The biosynthetic pathway and biologic roles in early embryogenic morphogenesis and vulval morphogenesis of HS and chondroitin sulfate GAG have been elucidated in Caenorhabditis elegans [127].
T613 1449-1549 Sentence denotes The negative charges mediate the interaction of GAGs and their ligands through electrostatic forces.
T614 1550-1624 Sentence denotes Interaction of HSPG with ligands potentiates many virus infectious cycles.
T615 1625-1897 Sentence denotes For examples, adeno-associated virus, human T cell lymphotropic virus type 1, human papilloma virus 16, herpes viruses, hepatitis B and C viruses, Kaposi’s sarcoma-associated herpesvirus, human papilloma viruses and Merkel cell polyoma virus recognize the HSPGs [128,129].
T616 1898-2005 Sentence denotes HSPGs increase virulence upon interaction with viral factors required for viral attachment and replication.
