| Enzyme name: TBL3 UniProt ID: Q8LED3 Gene name: TBL3/AT5G01360 Gene GenBank ID: 830298 | Synthesized dimer: Ac(1-3)bDXylp Status: indirect evidence in vivo Confirmation methods: double mutation ID: 1867 Notes: The tbl3/tbl31 double mutant had a specific reduction in 3-O-monoacetylation of xylan. | Organism (ID 9805): Arabidopsis thaliana Organ/tissue: stem Full structure (ID 34251): | Yuan et al. 2016a DOI: 10.1093/pcp/pcv172 |
| Enzyme name: TBL31 Gene name: TBL33/AT1G73140 Gene GenBank ID: 843645 | Synthesized dimer: Ac(1-3)bDXylp Status: indirect evidence in vivo Confirmation methods: double mutation ID: 1868 Notes: The tbl3/tbl31 double mutant had a specific reduction in 3-O-monoacetylation of xylan. | Organism (ID 9805): Arabidopsis thaliana Organ/tissue: stem Full structure (ID 34251): | |
| Enzyme name: TBL29 / ESK1 UniProt ID: Q9LY46.1 Gene name: ESK1 / AT3G55990 Gene GenBank ID: 824765 | Synthesized dimer: Ac(1-3)bDXylp Donor (ID 34252): Ac(1-?)Subst // Subst = CoA (substituted at S) Acceptor (ID 34253): -4)bDXylp(1- Status: semi-direct evidence in vivo Confirmation methods: in vitro (purified protein), mutation ID: 1870 Notes: TBL29 / ESK1 predominantly transfers the acetyl group to 2C of bDXylp. TBL29/ESK1 adds up to five acetyl groups to xylooligosaccharides with n ≥13. The levels of 2-O- and 3-O-monoacetylation of xylosyl residues in xylan are specifically reduced in the esk1 mutant. An idealized structure is shown. | Organism (ID 9805): Arabidopsis thaliana Organ/tissue: stem Full structure (ID 34254): | Urbanowicz et al. 2014 DOI: 10.1111/tpj.12643 Yuan et al. 2016b DOI: 10.1371/journal.pone.0146460 Yuan et al. 2013 DOI: 10.1093/pcp/pct070 Xiong et al. 2013 DOI: 10.1093/mp/sst014 |
| Enzyme name: TBL32 UniProt ID: Q9SRL3.1 Gene name: AT3G11030 Gene GenBank ID: 820274 | Synthesized dimer: Ac(1-3)bDXylp Donor (ID 34252): Ac(1-?)Subst // Subst = CoA (substituted at S) Acceptor (ID 34255): -4)[aDGlcpA(1-2)]bDXylp(1- Status: indirect evidence in vivo Confirmation methods: double mutation of tbl32/tbl33 ID: 1871 Notes: TBL32 and TBL33 are putative acetyltransferases mediating acetyl substitutions at O-3 of 2-O-GlcA-substituted xylosyl residues in xylan; they are also involved in xylan 3-O-monoacetylation and 2,3-di-O-acetylation. | Organism (ID 9805): Arabidopsis thaliana Organ/tissue: leaf, root, stem Full structure (ID 34256): | Yuan et al. 2016b DOI: 10.1371/journal.pone.0146460 |
