Dimerization of RsbS. (a) Oligomeric state of RsbS measured by SEC-MALS. The calculated molecular mass of RsbS was 24.9 kDa, which is close to that of a dimer (the molecular weight of a monomer is 13.3 kDa). (b) Binding interfaces in the RsbS crystal. Two dimeric interfaces in the crystal structure of RsbS are shown in the red and blue rectangular boxes. The RsbS hexamer in the red circle is formed by crystallographic and noncrystallographic interfaces, whereas the RsbS pentamer in the black circle is formed by a noncrystallographic interface (the asymmetric unit).
