2.A.121.1.4
Sulfate uptake porter of 246 aas and 4 or 5 TMSs.  CysZ from Pseudomonas denitrificans assembles as a trimer of antiparallel dimers, and the CysZ structures from two other species recapitulate dimers from this assembly. Mutational studies highlighted the functional relevance of conserved CysZ residues (Assur Sanghai et al. 2018).
