Abstract
We studied the binding of Junin virus (Arenaviridae) glycoproteins, G1 and G2, to two insolubilized lectins. The results showed that mannose, N-acetyl-glucosamine and galactose residues were exposed on G2, while only the latter predominated on G1. Heterogeneity of carbohydrate chains was found in G2, the only glycoprotein that was iodinated by the lactoperoxidase method.
On étudie l'interaction des glycoprotéines (G1 et G2) du virus Junín, appartenant à la famille des Arenaviridae, avec deux lectines insolubilisées. Les résultats montrent la présence de mannose, de N-acétyl-glucosamine et de galactose dans G2, alors que dans G1 le galactose est prédominant.
On observe une hétérogénéité dans la composition des oligosides de l'unique protéine d'enveloppe, G2, que l'on peut iodiner avec la lactoperoxydase.
