Sucrose 6F-alpha-galactosyltransferase () is an enzyme that catalyzes the chemical reaction

The two substrates of this enzyme characterised from sesame are sucrose and UDP-galactose. Its products are planteose and uridine diphosphate (UDP).

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-galactose:sucrose 6F-alpha-D-galactosyltransferase. Other names in common use include uridine diphosphogalactose-sucrose 6F-alpha-galactosyltransferase, UDPgalactose:sucrose 6fru-alpha-galactosyltransferase, and sucrose 6F-alpha-galactotransferase.
