2.4.99.18	endoplasmic reticulum	multiple oligosaccharyl transferase isoforms with different affinities for the translocon and ribosome and with heterogeneous subunit composition might exist in the endoplasmic reticulum membrane, thereby providing a means of regulating protein N-glycosylation	5783	677125	
2.4.99.18	endoplasmic reticulum	N-linked glycosylation occurs in the endoplasmic reticulum lumen by the membrane associated oligosaccharyltransferase enzyme complex	5783	-, 758885	
2.4.99.18	endoplasmic reticulum	oligosaccharyl transferase has a large domain in the lumenal side of endoplasmic reticulum where the catalysis occurs. The lumenal domain mainly comprises the catalytic Stt3p, the donor substrate-recognizing Wbp1p, and the acceptor substrate-recognizing Ost1p	5783	-, 690092	
2.4.99.18	endoplasmic reticulum	OST48, ribophorin I and ribophorin II possess a type I membrane topology with the bulk of their polypeptide chains directed to towards the lumen of the endoplasmic reticulum	5783	488512
