| - | [[ | + | [[https://www.uniprot.org/uniprot/STXA_BP933 STXA_BP933]] The A subunit is responsible for inhibiting protein synthesis through the catalytic inactivation of 60S ribosomal subunits. After endocytosis, the A subunit is cleaved by furin in two fragments, A1 and A2: A1 is the catalytically active fragment, and A2 is essential for holotoxin assembly with the B subunits. [[https://www.uniprot.org/uniprot/STXB_BP933 STXB_BP933]] The B subunit is responsible for the binding of the holotoxin to specific receptors on the target cell surface, such as globotriaosylceramide (Gb3) in human intestinal microvilli. |
