15215498-4	2004	C6ST-1 catalyzes the modifying step of chondroitin sulfate (CS) synthesis by transferring sulfate to the C-6 position of the N-acetylgalactosamine of chondroitin.	Chondroitin	39-50	carbohydrate sulfotransferase 3	Homo sapiens	0-6	
9147050-1	1997	We have previously shown that chondroitin 6-sulfotransferase (C6ST) catalyzes transfer of sulfate not only to position 6 of GalNAc residue of chondroitin but also to position 6 of Gal residue of keratan sulfate.	Chondroitin	30-41	carbohydrate sulfotransferase 3	Homo sapiens	62-66	
9147050-10	1997	The recombinant C6ST also catalyzed sulfation of the sialyl lactosamine oligosaccharides, indicating that a single protein catalyzes sulfation of chondroitin, keratan sulfate, and sialyl lactosamine oligosaccharides.	Chondroitin	146-157	carbohydrate sulfotransferase 3	Homo sapiens	16-20	
9639683-2	1998	C6ST catalyzes the transfer of sulfate from 3"-phosphoadenosine 5"-phosphosulfate to carbon 6 of the N-acetylgalactosamine residues of chondroitin.	Chondroitin	135-146	carbohydrate sulfotransferase 3	Homo sapiens	0-4
