Biochemical and structural characterization of the human gut microbiome metallopeptidase IgAse provides insight into its unique specificity for the Fab' region of IgA1 and IgA2.
Human immunoglobulin A (IgA), comprising the isotypes IgA1 and IgA2, protects ~400 m2 of mucosal surfaces against microbial infections but can also lead to aberrant IgA deposits that cause disease. Certain bacteria have evolved peptidases that cleave the hinge between the Fab and Fc fragments of IgA...
