Activities in Family	Hexosyltransferases (EC 2.4.1.-); [inverting] UDP-Galf: [LPS/O-antigen] α-glucoside β-1,6-galactofuranosyltransferase (EC 2.4.1.-);
3D Structure Status	GT-B
Note	Family created after Zhou et al. (2010) [PMID: 20164186] who demonstrated the glycosyltransferase activity in the Streptococcus parasanguinis protein Gtf3. The enzyme is predicted to have a retaining mechanism [PMID=21653318] based on structural similarity to GT4, GT5 and GT20 structures; however, direct proof of the stereochemistry of the glycosidic bond formed is missing.
Statistics	GenBank accession (1992); Uniprot accession (4); PDB accession (3); 3D entries (2); cryst (0)
