Members of this family transfer activated sugars to a variety of substrates, including glycogen, Fructose-6-phosphate and lipopolysaccharides. Members of this family transfer UDP, ADP, GDP or CMP linked sugars. The eukaryotic glycogen synthases may be distant members of this family.

Sucrose synthases are sucrose-cleaving enzymes that provides UDP-glucose and fructose for various metabolic pathways.

This represents the first GT-B domain (also referred to as GT-BN in [1] of sucrose synthases, while the second one, at the C-terminal (GT-BC), is represented in Pfam:PF00534 [1,2]. The substrates of these proteins (UDP-Glc or UDP and fructose) bound in the cleft between the GT-B domains [1].
