Glycosyltransferase family 29 (GT29) comprises enzymes with a number of known activities; sialyltransferase (EC:2.4.99), beta-galactosamide alpha-2,6-sialyltransferase (EC:, alpha-N-acetylgalactosaminide alpha-2,6-sialyltransferase (EC:, beta-galactoside alpha-2,3-sialyltransferase (EC:, N-acetyllactosaminide alpha-2,3-sialyltransferase (EC:, alpha-N-acetyl-neuraminide alpha-2,8-sialyltransferase (EC:; lactosylceramide alpha-2,3-sialyltransferase (EC: These enzymes use a nucleotide monophosphosugar as the donor (CMP-NeuA) instead of a nucleotide diphosphosugar.

Sialyltransferase may be responsible for the synthesis of the sequence NEUAC-Alpha-2,3-GAL-Beta-1,3-GALNAC-, found on sugar chains O-linked to thr or ser and also as a terminal sequenec on certain gagnliosides. These enzymes catalyse sialyltransfer reactions during glycosylation, and are type II membrane proteins.
