Predicted structural features of NOMO. (A) An AlphaFold3 model prediction of FL human NOMO1 resolves twelve Ig-like folds, colored by Ig domains depicted as balls in the bottom right cartoon. NOMO1 is represented in two views related by a 180° rotation, as indicated. (B) Magnification of the interface formed by Ig 1/10/11 with D70-K927 and D121-R903 salt bridges labeled. (C) An alternative view of the Ig 1/10/11 interface with K66-D994-K931-E993 salt bridges labeled. (D) Ig 1–2 and Ig 10–11 interface conservation. Inset, ConSurf color-coding scheme from (1) variable to (9) conserved. (E) Sequence conservation of regions around and including the salt bridges shown in B and C, colored by >80% conservation.
