BIOCHEMISTRY Correction for “Cryo-EM structures show the mechanistic basis of pan-peptidase inhibition by human α2-macroglobulin,” by Daniel Luque, Theodoros Goulas, Carlos P. Mata, Soraia R. Mendes, F. Xavier Gomis-Rüth, and José R. Castón, which published May 2, 2022; 10.1073/pnas.2200102119 (Proc. Natl. Acad. Sci. U.S.A. 119, e2200102119).
The authors note that: “During the process of submission, an article appeared in the Journal of Molecular Biology, in which conclusions that were similar to a part of ours were reported for an ortholog of human α2-macroglobulin from the African clawed frog Xenopus laevis, (Y. Arimura and H. Funabiki. J. Mol. Biol. 434: 167413, 2022).”
The article has been updated to add a reference to Arimura and Funabiki.
