Functioning of potassium and magnesium in photosynthesis, photosynthate translocation and photoprotection.

open access: yesPhysiologia Plantarum : An International Journal for Plant Biology, 2018
Potassium (K) and magnesium (Mg) are mineral nutrients that are required in large quantities by plants. Both elements critically contribute to the process of photosynthesis and the subsequent long-distance transport of photoassimilates. If K or Mg is not

Mobility of the SecA 2-helix-finger is not essential for polypeptide translocation via the SecYEG complex [PDF]

open access: yes, 2012
The bacterial ATPase SecA and protein channel complex SecYEG form the core of an essential protein translocation machinery. The nature of the conformational changes induced by each stage of the hydrolytic cycle of ATP and how they are coupled to protein ...

Structure of a translocation signal domain mediating conjugative transfer by Type IV secretion systems [PDF]

open access: yes, 2013
Relaxases are proteins responsible for the transfer of plasmid and chromosomal DNA from one bacterium to another during conjugation. They covalently react with a specific phosphodiester bond within DNA origin of transfer sequences, forming a nucleo ...

Phytoavailability of Geogenic Arsenic and Its Partitioning in Soil: a Case Of Study in a Thermal Area of Central Italy

open access: yesEQA, 2016
Arsenic (As) is an ubiquitous metalloid that is introduced into the environment from both anthropogenic and geochemical sources. The As can be introduced in food chain through plants grown on polluted soil and/or contaminated irrigation water.
