FunFam 24820: Uncharacterized protein

There are 1 EC terms in this cluster

Please note: EC 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.

Note: 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.

Hyaluronan synthase. [EC: 2.4.1.212]
(1) UDP-alpha-N-acetyl-D-glucosamine + beta-D-glucuronosyl-(1->3)-N- acetyl-beta-D-glucosaminyl-(1->4)-(nascent hyaluronan) = UDP + N-acetyl- beta-D-glucosaminyl-(1->4)-beta-D-glucuronosyl-(1->3)-N-acetyl-beta-D- glucosaminyl-(1->4)-(nascent hyaluronan). (2) UDP-alpha-D-glucuronate + N-acetyl-beta-D-glucosaminyl-(1->4)-beta-D- glucuronosyl-(1->3)-(nascent hyaluronan) = UDP + beta-D-glucuronosyl- (1->3)-N-acetyl-beta-D-glucosaminyl-(1->4)-beta-D-glucuronosyl-(1->3)- (nascent hyaluronan).
  • Adds GlcNAc to nascent hyaluronan when the non-reducing end is GlcA, but it adds GlcA when the non-reducing end is GlcNAc.
  • Highly specific for UDP-GlcNAc and UDP-GlcA; no copolymerization is observed if either is replaced by UDP-Glc, UDP-Gal, UDP-GalNAc or UDP-GalA.
