Assignment of the glycosyltransferase variants is based on amino acid sequence comparisons with variants of known specificities.

on: indicates that a gene has no frame-shift mutation.

Mono-sialyl.: the glycosyltransferase is specific for mono-sialylated acceptors.

Non-sialyl.: the glycosyltransferase is specific for non-sialylated acceptors.

off: indicates that a gene is inactive because of a frame-shift mutation.

Cst-II variants: mono-: monofunctional, Cst-II has α-2,3-sialyltransferase activity. bi-: bifunctional, Cst-II has both α-2,3-sialyltransferase and α-2,8-sialyltransferase activity.

GalT: β-1,4-galactosyltransferase that uses Glcβ-1,2-HepII- as acceptor.
