CC -!- FUNCTION: Converts D-glucuronic acid residues adjacent to N-sulfate
CC sugar residues to L-iduronic acid residues, both in maturing heparan
CC sulfate (HS) and heparin chains (PubMed:16156897, PubMed:25568314).
CC Plays a role in dorso-ventral axis specification during early
CC development, together with glcea, where it may potentiate signaling via
CC the BMP pathway (PubMed:16156897). {ECO:0000269|PubMed:16156897,
CC ECO:0000269|PubMed:25568314}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[heparosan-N-sulfate](n) = [heparan-N-sulfate](n);
CC Xref=Rhea:RHEA:20197, Rhea:RHEA-COMP:9556, Rhea:RHEA-COMP:9557,
CC ChEBI:CHEBI:58041, ChEBI:CHEBI:58287; EC=5.1.3.17;
CC Evidence={ECO:0000269|PubMed:25568314, ECO:0000305|PubMed:16156897};
CC -!- ACTIVITY REGULATION: Inhibited by O-sulfated heparin, which is produced
CC by a downstream step in the heparin biosynthesis pathway.
CC {ECO:0000269|PubMed:25568314}.
CC -!- PATHWAY: Glycan metabolism; heparan sulfate biosynthesis.
CC {ECO:0000305|PubMed:16156897, ECO:0000305|PubMed:25568314}.
CC -!- PATHWAY: Glycan metabolism; heparin biosynthesis.
CC {ECO:0000305|PubMed:16156897, ECO:0000305|PubMed:25568314}.
CC -!- SUBUNIT: Homodimer. {ECO:0000269|PubMed:25568314}.
CC -!- SUBCELLULAR LOCATION: Golgi apparatus membrane
CC {ECO:0000250|UniProtKB:Q9EPS3}; Single-pass type II membrane protein
CC {ECO:0000250|UniProtKB:Q9EPS3}.
CC -!- DEVELOPMENTAL STAGE: Detected from 0.5 to 48 hours post-fertilization
CC (hpf) (PubMed:16156897). At 24-36 hpf, expressed in adaxial mesoderm,
CC somites, notochord, floorplate, hypochord, tail bud, eye,
CC telencephalon, diencephalon, midbrain, hindbrain and otic vesicle
CC (PubMed:17195182). {ECO:0000269|PubMed:16156897,
CC ECO:0000269|PubMed:17195182}.
CC -!- DISRUPTION PHENOTYPE: Double morpholino knockdown of both glcea and
CC glceb results in dorsalized embryos, with reduced ventral tail fin,
CC kinked tail and an enlarged heart cavity. In severe cases there is
CC significant shortening of the body and tail coiling. Epimerase activity
CC is reduced. Expression of the dorsalizing factor chordin is expanded,
CC whereas expression of bmp2b is reduced, notably in the tail. Expression
CC of gata1 in blood islets is also reduced.
CC {ECO:0000269|PubMed:16156897}.
CC -!- SIMILARITY: Belongs to the D-glucuronyl C5-epimerase family.
CC {ECO:0000305}.
CC -!- CAUTION: It is uncertain whether Met-1 or Met-2 is the initiator.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
