PA0572 of P. aeruginosa is an inhibitor of PSGL-1, also known as an immunomodulating metalloprotease of P. aeruginosa (IMPa). IMPa prevents neutrophil extravasation and thereby protects P. aeruginosa from neutrophil attack [1]. It belongs to the peptidase M60 family Pfam:PF13402. This entry represents the N-terminal alpha/beta-fold domain [2].
