Abstract

The archaeal S-layer represents one of the most ancient and versatile cell surface structures, playing critical roles in maintaining cellular integrity, mediating environmental interactions, and enabling cellular flexibility. Recent advances in structural biology, including cryo-electron microscopy and computational tools like AlphaFold, have unveiled the structural intricacies and diversity of these proteinaceous layers. This review highlights the biogenesis, structural assembly, evolutionary adaptations, and functional roles of archaeal S-layers, focusing on model organisms such as Sulfolobus acidocaldarius and Haloferax volcanii. Additionally, we discuss outstanding questions and future directions for the study of archaeal cell envelopes.
