Three‐dimensional structure of the surface layer of Wolinella recta

Academic Article


  • The three‐dimensional structure of the crystalline surface layer (S‐layer) of Wolinella recta ATCC 33238T, a gram‐negative, anaerobic periodontopathogen, was determined to 3.8 nm resolution by electron microscopy and digital image processing. The S‐layer protein is closely associated with the outer bacterial membrane, and shows p6 symmetry with lattice spacing and thickness of 21 nm and 15 nm, respectively. The funnel‐shaped subunits consist of 6 heavy domains located round a common base at the sixfold axis, and communicate with the adjacent subunits through a lighter domain at the threefold axis (M6C3 arrangement).
