25186462-2	2014	A distinct feature of DS is the presence of iduronic acid, produced by the two enzymes, DS-epimerase 1 and 2, which are encoded by Dse and Dsel, respectively.	Iduronic Acid	44-57	dermatan sulfate epimerase-like	Mus musculus	139-143	
22496542-1	2012	Dermatan sulfate epimerase 2 (DS-epi2), together with its homolog DS-epi1, transform glucuronic acid into iduronic acid in DS polysaccharide chains.	Iduronic Acid	106-119	dermatan sulfate epimerase-like	Mus musculus	0-28	
22496542-1	2012	Dermatan sulfate epimerase 2 (DS-epi2), together with its homolog DS-epi1, transform glucuronic acid into iduronic acid in DS polysaccharide chains.	Iduronic Acid	106-119	dermatan sulfate epimerase-like	Mus musculus	30-37	
21177331-4	2011	In this study, to clarify the distribution of the DS-type structure in the brain during development, the expression patterns of DS epimerase 1 (DS-epi1) and DS-epi2, both of which convert d-glucuronic acid into IdoA, were investigated by in situ hybridization.	Iduronic Acid	211-215	dermatan sulfate epimerase-like	Mus musculus	157-164	
19687302-1	2009	Dermatan sulfate epimerase 1 (DS-epi1) and DS-epi2 convert glucuronic acid to iduronic acid in chondroitin/dermatan sulfate biosynthesis.	Iduronic Acid	78-91	dermatan sulfate epimerase-like	Mus musculus	43-50
