Structure-based analysis of CysZ-mediated cellular uptake of sulfate
Sulfur, most abundantly found in the environment as sulfate (SO 4 2- ), is an essential element in metabolites required by all living cells, including amino acids, co-factors and vitamins. However, current understanding of the cellular delivery of SO 4 2- at the molecular level is limited. CysZ has been described as a SO 4 2- permease, but its sequence family is without known structural precedent. Based on crystallographic structure information, SO 4 2- binding and flux experiments, we provide insight into the molecular mechanism of CysZ-mediated translocation of SO 4 2- across membranes. CysZ structures from three different bacterial species display a hitherto unknown fold and have subunits organized with inverted transmembrane topology. CysZ from Pseudomonas denitrificans assembles as a trimer of antiparallel dimers and the CysZ structures from two other species recapitulate dimers from this assembly. In conclusion, mutational studies highlight the functional relevance of conserved CysZ residues.

MSAViewer: interactive JavaScript visualization of multiple sequence alignments
The MSAViewer is a quick and easy visualization and analysis JavaScript component for Multiple Sequence Alignment data of any size. Core features include interactive navigation through the alignment, application of popular color schemes, sorting, selecting and filtering. The MSAViewer is ‘web ready’: written entirely in JavaScript, compatible with modern web browsers and does not require any specialized software. The MSAViewer is part of the BioJS collection of components.
