9.B.142.3.14
The glycosyltransferase complex consisting of 8 subunits, all integral membrane proteins. The high resolution 3-dimensional structure has been elucidated (Wild et al. 2018). The catalytic subunit is the STT3 protein of 718 aas and 13 TMSs. The other subunits have 1 - 6 TMSs. The function of the complex is glycosylation of newly synthesized proteins on Asn with Glc3Man9 GlcNac2.
