FIG 3 .

Model of MamC-GBP and CheW₁-EGFP interaction. CheW₁-EGFP localizes distinctly at the cell poles if expressed chromosomally in the wild-type and ΔmamJ backgrounds (top right and left). If MamC-GBP is coexpressed in the wild type (bottom left), CheW₁-EGFP is depleted completely from the poles. Expression of MamC-GBP in the ΔmamJ CheW₁-EGFP background leads to recruitment of whole magnetosomes to the cell poles (bottom right). Expression of monovalent and divalent nanobodies on a magnetosomes and interaction with CheW₁-EGFP is illustrated in the inset. Expressed proteins are illustrated in same colors as genes.
