This detailed volume presents cutting-edge research protocols to study the structure and dynamics of bacterial and archaeal motility systems using bacterial genetics, molecular biology, biochemistry, biophysics, structural biology, cell biology, microscopy imaging, and molecular dynamics simulation. Beginning with a section on bacterial flagellar protein export and assembly, the book continues with chapters covering flagella-driven motility of bacteria, archaella-driven motility of archaea, type IV-driven twitching motility of bacteria, as well as adhesion-based gliding motility of bacteria and other unique motility systems. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
