26900446-3	2016	Dermatan sulfate epimerase 1 (DS-epi1) is the predominant enzyme during the formation of iduronic acid residues in the glycosaminoglycan dermatan sulfate.	Iduronic Acid	89-102	dermatan sulfate epimerase	Homo sapiens	0-28	
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.	Iduronic Acid	101-116	dermatan sulfate epimerase	Homo sapiens	0-28	
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.	Iduronic Acid	101-116	dermatan sulfate epimerase	Homo sapiens	30-37	
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.	Iduronic Acid	145-158	dermatan sulfate epimerase	Homo sapiens	169-195	
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).	Iduronic Acid	120-133	dermatan sulfate epimerase	Homo sapiens	207-221	
29976758-2	2018	Previous in vitro studies indicated that without association with other enzymes, DS-epi1 activity produces structures that have only a few adjacent iduronic acid units.	Iduronic Acid	148-161	dermatan sulfate epimerase	Homo sapiens	81-88	
29976758-8	2018	The cooperation of DS-epi1 with D4ST1 may therefore explain the processive mode of the formation of iduronic acid blocks.	Iduronic Acid	100-113	dermatan sulfate epimerase	Homo sapiens	19-26	
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.	Iduronic Acid	160-164	dermatan sulfate epimerase	Homo sapiens	169-195

Iduronic Acid	160-164	dermatan sulfate epimerase	Homo sapiens	197-212	
27101845-5	2016	We demonstrate that DS-epi1 is important for the generation of isolated iduronic acid residues in chondroitin sulfate (CS)/DS proteoglycans in early Xenopus embryos.	Iduronic Acid	72-85	dermatan sulfate epimerase	Homo sapiens	20-27	
26900446-3	2016	Dermatan sulfate epimerase 1 (DS-epi1) is the predominant enzyme during the formation of iduronic acid residues in the glycosaminoglycan dermatan sulfate.	Iduronic Acid	89-102	dermatan sulfate epimerase	Homo sapiens	30-37	
19188366-6	2009	By using a short interfering RNA approach, we found that DS-epi2 and DS-epi1 are both involved in the biosynthesis of the iduronic acid blocks in fibroblasts and that DS-epi2 can also synthesize the hybrid structures.
