SUBTILASE CYTOTOXIN B SUBUNIT MUTANT

A mutant subtilase cytotoxin B subunit protein is provided which can bind glycans having α2-3-linked N-glycolylneuraminic acid and glycans having α2-6-linked N-glycolylneuraminic acid. The mutant SubB protein has deletions of one or more of the amino acid sequence TTSTE and has a previously undescri...

Zusammenfassung:A mutant subtilase cytotoxin B subunit protein is provided which can bind glycans having α2-3-linked N-glycolylneuraminic acid and glycans having α2-6-linked N-glycolylneuraminic acid. The mutant SubB protein has deletions of one or more of the amino acid sequence TTSTE and has a previously undescribed ability to bind glycans having α2-6-linked N-glycolylneuraminic acid, while not losing the ability to bind glycans having α2-3-linked N-glycolylneuraminic acid.
