Crystal structure of heparan sulfate lyase HepC mutant from Pedobacter heparinus
Function
[HEPC_PEDHD] Specifically cleaves heparan sulfate-rich regions of acidic polysaccharides. Does not act on N,O-desulfated glucosamine or N-acetyl-O-sulfated glucosamine linkages. Functions in cleaving metazoan heparan sulfate and providing carbon, nitrogen and sulfate sources for microorganisms.[1] [2]
About this Structure
4mmi is a 1 chain structure. Full crystallographic information is available from OCA.
