Crystal structure of SmoS from S. meliloti 1021. (a) Cartoon representation of the SmoS quaternary structure. SmoS forms a homotetramer; the individual monomers are coloured magenta, green, blue and yellow. (b) Cartoon representation of the SmoS monomer (grey). Secondary-structure elements are labelled numerically (α, α-helix; β, β-strand; π, π-helix; η, 310-helix). |
