Figure 1. Polymerisation of MamK.

(a) Dynamic light scattering of MamK (20 µM) in polymerisation buffer, pH 7.0 at 30°C. The insert shows the concentration dependent polymerisation of MamK under the same conditions (b) recorded net auto-correlation function G²(τ) (generated from the reaction of MamK in low salt polymerisation buffer revealing the quality of the second order autocorrelation fit (c) Dynamic light scattering of MamK (20 µM) in high salt polymerisation buffer (100 mM Tris-HCl, 14 mM MgCl₂, 100 mM NaCl and 30 mM KCl) pH 7.0 at 30°C. (d) recorded net auto-correlation function G²(τ) (generated from the reaction of MamK in high salt polymerisation buffer revealing the quality of the second order autocorrelation fit). Polymerisation was initiated by addition of ATP (0.2 mM) and the scattering intensity was measured after a 5 minute incubation period of the assay mixture in the temperature chamber. Light scattering was monitored using a 90° optics scattering angle at a wavelength of 400 nm. Data accumulation period Δτ = 10 µs.
