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

Type IV Pili as a Therapeutic Target [PDF]
Trends in Microbiology, 2019 In the age of antibiotic resistance, strategies targeting virulence traits of bacteria are the focus of intense study. Two such studies came out independently a week apart showing that bacterial type IV pili are a promising therapeutic target.

Gram-Positive Type IV Pili and Competence
Microbiology Spectrum, 2019 ABSTRACT Type IV pili (T4P) are remarkable bacterial surface appendages that carry out a range of functions. Various types of T4P have been identified in bacteria and archaea, making them almost universal structures in prokaryotes.

Type IV pili: e pluribus unum? [PDF]
Molecular Microbiology, 2008 SummaryThe widespread role of pili as colonization factors in pathogens has long been recognized in Gram‐negative bacteria and more recently in Gram‐positive bacteria, making the study of these hair‐like filaments a perennial hot topic for research. No other pili are found in as many or as diverse bacteria as type IV pili.
