Manganese acquisition is facilitated by PilA in the cyanobacterium Synechocystis sp. PCC 6803. [PDF]

open access: yesPLoS ONE, 2017
Manganese is an essential element required by cyanobacteria, as it is an essential part of the oxygen-evolving center of photosystem II. In the presence of atmospheric oxygen, manganese is present as manganese oxides, which have low solubility and ...

Characterization of four type IV pilin homologues in Stigmatella aurantiaca DSM17044 by heterologous expression in Myxococcus xanthus. [PDF]

open access: yesPLoS ONE, 2013
As prokaryotic models for multicellular development, Stigmatella aurantiaca and Myxococcus xanthus share many similarities in terms of social behaviors, such as gliding motility.

Characterization of Zoospore Type IV Pili in Actinoplanes missouriensis [PDF]

open access: yesJournal of Bacteriology, 2019
Bacterial zoospores are interesting cells in that their physiological state changes dynamically: they are dormant in sporangia, show temporary mobility after awakening, and finally stop swimming to germinate in niches for vegetative growth. However, the cellular biology of a zoospore remains largely unknown.

Predicting and Interpreting the Structure of Type IV Pilus of Electricigens by Molecular Dynamics Simulations

open access: yesMolecules, 2017
Nanowires that transfer electrons to extracellular acceptors are important in organic matter degradation and nutrient cycling in the environment. Geobacter pili of the group of Type IV pilus are regarded as nanowire-like biological structures.

: analysis of pili and LPS in emerging Brazilian strains

open access: yesTherapeutic Advances in Vaccines and Immunotherapy, 2020
Background: Neisseria meningitidis is the main cause of bacterial meningitis in Brazil, where the main serogroups isolated are B and C; however, the serogroup W has recently emerged.

Archaeal type IV pili stabilize Haloferax volcanii biofilms in flow

open access: yesbioRxiv, 2023
Biofilms represent a prevalent lifestyle of unicellular organism that confers protection to external challenges. The mechanisms by which archaea form biofilms are however not entirely clear. H.

Appendages of the Cyanobacterial Cell

open access: yesLife, 2015
Extracellular non-flagellar appendages, called pili or fimbriae, are widespread in gram-negative bacteria. They are involved in many different functions, including motility, adhesion, biofilm formation, and uptake of DNA.

Identification of an additional minor pilin essential for piliation in the archaeon Methanococcus maripaludis. [PDF]

open access: yesPLoS ONE, 2013
Methanococcus maripaludis is an archaeon with two studied surface appendages, archaella and type IV-like pili. Previously, the major structural pilin was identified as MMP1685 and three additional proteins were designated as minor pilins (EpdA, EpdB and ...

Pseudomonas aeruginosa orchestrates twitching motility by sequential control of type IV pili movements

open access: yesNature Microbiology, 2019
Prokaryotes have the ability to walk on surfaces using type IV pili (TFP), a motility mechanism known as twitching1,2. Molecular motors drive TFP extension and retraction, but whether and how these movements are coordinated is unknown3.

Bacteria use type-IV pili to slingshot on surfaces [PDF]

open access: yesProceedings of the National Academy of Sciences, 2011
Bacteria optimize the use of their motility appendages to move efficiently on a wide range of surfaces prior to forming multicellular bacterial biofilms. The “twitching” motility mode employed by many bacterial species for surface exploration uses type-IV pili (TFP) as linear actuators to enable directional crawling. In addition to
