Type IV pili: dynamics, biophysics and functional consequences
Sign Up to like & getrecommendations! Published in 2019 at "Nature Reviews Microbiology"
DOI: 10.1038/s41579-019-0195-4
Abstract: The surfaces of many bacteria are decorated with long, exquisitely thin appendages called type IV pili (T4P), dynamic filaments that are rapidly polymerized and depolymerized from a pool of pilin subunits. Cycles of pilus extension,… read more here.

DOI: 10.1126/science.adl0635
Abstract: The retractile type IV pilus (T4P) is important for virulence of the opportunistic human pathogen Pseudomonas aeruginosa. The single-stranded RNA (ssRNA) phage PP7 binds to T4P and is brought to the cell surface through pilus… read more here.

DOI: 10.1128/jb.00859-16
Abstract: ABSTRACT For Pseudomonas aeruginosa, levels of cyclic di-GMP (c-di-GMP) govern the transition from the planktonic state to biofilm formation. Type IV pili (T4P) are crucial determinants of biofilm structure and dynamics, but it is unknown… read more here.

DOI: 10.3389/fmicb.2022.839711
Abstract: Bacterial type 4 pili (T4P) are extracellular polymers that serve both as adhesins and molecular motors. Functionally, they are involved in adhesion, colony formation, twitching motility, and horizontal gene transfer. T4P of the human pathogen… read more here.
