Extended Data Fig. 7: PgBAM structural features.
From: Structure of a distinct β-barrel assembly machinery complex in the Bacteroidota
a, Two cryo-EM classes of PgBAM shown at high (left) and low (right) contour. The periplasmic density observed in class 2 is assumed to correspond to PgBamD and/or PgBamA POTRA domain 5. b, Glycosylation sites observed in the PgBAM structure. Mannose units (space filling representation) were built into the glycan density to stabilise protein model refinement. Insets show close-ups of representative model density at glycosylation sites on BamI (Ser84, Ser115) and BamG (Ser85). c, Model-density fit of the PgBamH lipid anchor at the PgBamAG barrel interface.
