FunFam 32: Chondroitin sulfate ABC exolyase

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 6 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Magnesium ion binding GO:0000287
Interacting selectively and non-covalently with magnesium (Mg) ions.
1 C5G6D7 (/IDA)
Calcium ion binding GO:0005509
Interacting selectively and non-covalently with calcium ions (Ca2+).
1 C5G6D7 (/IDA)
Hyaluronate lyase activity GO:0030340
Catalysis of the reaction: hyaluronate = n 3-(4-deoxy-beta-D-gluc-4-enuronosyl)-N-acetyl-D-glucosamine.
1 Q8A2I1 (/IDA)
Chondroitin AC lyase activity GO:0030341
Catalysis of the eliminative degradation of polysaccharides containing 1,4-beta-D-hexosaminyl and 1,3-beta-D-glucuronosyl linkages to disaccharides containing 4-deoxy-beta-D-gluc-4-enuronosyl groups.
1 Q8A2I1 (/IDA)
Chondroitin B lyase activity GO:0033999
Catalysis of the reaction: dermatan sulfate = n 4-deoxy-beta-D-gluc-4-enuronosyl-(1,3)-N-acetyl-D-galactosamine 4-sulfate. This reaction is the eliminative cleavage of dermatan sulfate containing 1,4-beta-D-hexosaminyl and 1,3-beta-D-glucurosonyl or 1,3-alpha-L-iduronosyl linkages to disaccharides containing 4-deoxy-beta-D-gluc-4-enuronosyl groups to yield a 4,5-unsaturated dermatan-sulfate disaccharide (DeltaUA-GalNAC-4S). Chondroitin sulfate B is also known as dermatan sulfate.
1 Q8A2I1 (/IDA)
Chondroitin-sulfate-ABC exolyase activity GO:0034001
Catalysis of the exolytic cleavage of disaccharide residues from the non-reducing ends of both polymeric chondroitin sulfates and their oligosaccharide fragments.

1 Q8A2I1 (/IDA)
Dermatan sulfate catabolic process GO:0030209
