Endo-beta-N-acetylglucosaminidase EndoS2

UniProtKB accession:  T1WGN1

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Endoglucosidase that acts as a host immune evasion factor by mediating hydrolysis of the N-linked glycan from the Fc region of host immunoglobulin-gamma (IgG) during infection (PubMed:23865566, PubMed:27288408, PubMed:26156869, PubMed:30937380). Specifically catalyzes the hydrolysis of the beta-1,4 linkage between the first two N-acetylglucosamine residues of the complex-type N-linked glycan located on 'Asn-297' of the Fc region of IgG antibodies (IGHG1, IGHG2, IGHG3 or IGHG4), thereby preventing interaction between IgGs and Fc receptors and ability to activate the complement pathway (By similarity). Also able to cleave biantennary and sialylated glycans of host alpha-1-acid glycoprotein (ORM1 or ORM2) (PubMed:23865566, PubMed:27288408). Acts on N-linked glycans with or without core fucosylation (PubMed:26156869, PubMed:27288408, PubMed:30937380). In contrast to EndoS, also able to process oligomannose- or hybrid-type glycans (PubMed:26156869, PubMed:30937380). Specifically acts on IgGs; does not act on immunoglobulin alpha, beta, delta or mu (PubMed:26156869).
