FunFam 91: Glycosyltransferase

There are 3 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Anthocyanidin 3-O-glucosyltransferase. [EC: 2.4.1.115]
UDP-D-glucose + an anthocyanidin = UDP + an anthocyanidin-3-O-beta-D- glucoside.
  • The anthocyanidin compounds cyanidin, delphinidin, peonidin and to a lesser extent pelargonidin can act as substrates.
  • Does not catalyze glucosylation of the 5-position of cyanidin and does not act on flavanols such as quercetin and kaempferol (cf. EC 2.4.1.91).
  • In conjunction with EC 1.14.20.4, it is involved in the conversion of leucoanthocyanidin into anthocyanidin 3-glucoside.
  • It may act on the pseudobase precursor of the anthocyanidin rather than on the anthocyanidin itself.
  • Formerly EC 2.4.1.233.

Flavonol 3-O-glucosyltransferase. [EC: 2.4.1.91]
UDP-glucose + a flavonol = UDP + a flavonol 3-O-D-glucoside.
  • Acts on a variety of flavonols, including quercetin and quercetin 7-O-glucoside.
  • Different from EC 2.4.1.81.

Flavonol-3-O-glucoside L-rhamnosyltransferase. [EC: 2.4.1.159]
UDP-beta-L-rhamnose + a flavonol 3-O-beta-D-glucoside = UDP + a flavonol 3-O-(alpha-L-rhamnosyl-(1->6)-beta-D-glucoside).
  • A configuration-inverting rhamnosyltransferase that converts flavonol 3-O-glucosides to 3-O-rutinosides.
  • Also acts, more slowly, on rutin, quercetin 3-O-galactoside and flavonol 3-O-rhamnosides.
