GGDB:

HS6ST2はheparan sulfate-glucosamine 6-sulfotransferase 2をコードする。へパラン硫酸はHexAとGlcNAc/GlcNSO3の2糖繰り返しユニットに硫酸が付加した構造であるが、HS6STはN-sulfated GlcNAcの6位の硫酸化を触媒する。HS6STはヒトでは3種類のイソ酵素が存在し、発現組織や基質特異性が異なる。HS6ST2は長さの異なる2種類のアイソフォーム（HS6ST-2, HS6ST-2S）が存在するが、これらの基質特異性は異なる。全長型のHS6ST-2はIdo(2SO4)-GlcNSO3ユニットのGlcNSO3に硫酸を転移するが、HS6ST-2SはIdo(2SO4)-GlcNSO3ユニットに加えて、GlcA-GlcNSO3ユニットのGlcNSO3にも硫酸を転移する。
