Reaction: GalNAc is transferred onto 3a
- in pathway: Maturation of protein 3a
This COVID-19 event has been created by a combination of computational inference (see https://reactome.org/documentation/inferred-events) from SARS-CoV-1 data and manual curation, as described in the summation for the overall SARS-CoV-2 infection pathway.
A sialyltransferase adds a terminal sialic acid moiety to protein 3a with an O-linked glycosyl side chain. This glycosylated form later is associated with the virion (Oostra et al, 2006)
