Neuraminidase C (NanC)
Product summary
Neuraminidase C (NanC) from Streptococcus pneumoniae selectively cleaves terminal α2-3-linked sialic acids with limited activity toward α2-6 linkages, releasing free sialic acid. Its mild, controlled desialylation makes it useful for glycoprotein/glycan structural analysis, biopharmaceutical desialylation, production of analytical sialic-acid standards, and enzymatic synthesis or modification of glycoconjugates
Product Description
Neuraminidase C (NanC) from Streptococcus pneumoniae is a sialidase enzyme that cleaves terminal sialic acid residues from glycoconjugates, but with narrower substrate specificity compared to NanA and NanB. NanC preferentially acts on α2-3-linked sialic acids and exhibits limited activity toward α2-6 linkages. It typically releases free sialic acid rather than cyclic products and is believed to function synergistically with other pneumococcal neuraminidases in modulating host-pathogen interactions. Due to its selective yet less aggressive desialylation profile, NanC is useful in applications requiring controlled removal of specific sialic acid linkages while preserving overall glycan structure integrity.
