29976758-1	2018	During the biosynthesis of chondroitin/dermatan sulfate (CS/DS), a variable fraction of glucuronic acid is converted to iduronic acid through the activities of two epimerases, dermatan sulfate epimerases 1 (DS-epi1) and 2 (DS-epi2).	Glucuronic Acid	88-103	dermatan sulfate epimerase	Homo sapiens	207-221	
33815739-0	2021	The structure of human dermatan sulfate epimerase 1 emphasizes the importance of C5-epimerization of glucuronic acid in higher organisms.	Glucuronic Acid	101-116	dermatan sulfate epimerase	Homo sapiens	23-51	
33815739-1	2021	Dermatan sulfate epimerase 1 (DS-epi1, EC 5.1.3.19) catalyzes the conversion of d-glucuronic acid to l-iduronic acid on the polymer level, a key step in the biosynthesis of the glycosaminoglycan dermatan sulfate.	Glucuronic Acid	80-97	dermatan sulfate epimerase	Homo sapiens	0-28

31972438-1	2020	Dermatan sulfate (DS) is a glycosaminoglycan (GAG) that is produced through the epimerization of the glucuronic acid on chondroitin sulfate into iduronic acid (IduA) by dermatan sulfate epimerase (DS-epi) 1 and 2.	Glucuronic Acid	101-116	dermatan sulfate epimerase	Homo sapiens	169-195
