Figure 5: Model of peptidoglycan insertion based on AFM, fluorescence microscopy and STORM data.
From: Cell wall elongation mode in Gram-negative bacteria is determined by peptidoglycan architecture
Regions of porous architecture (dark bands in AFM images) are permissive for insertion of new peptidoglycan, which occurs when the elongation machinery is present, and PBP1A and LpoA are able to form a complex, resulting in the patchy pattern of insertion illustrated by STORM images.
