In metazoan organisms, the STT3A isoform from the oligosaccharyltransferase is localized next to the protein translocation route to catalyze co-translational N-linked glycosylation of proteins in the endoplasmic reticulum. eight accessories subunits. Herb and metazoan organisms encode two STT3 proteins (STT3A and STT3B) that are put together with a set of six shared OST subunits (ribophorins… Continue reading In metazoan organisms, the STT3A isoform from the oligosaccharyltransferase is localized
