Аннотация:Crystallization of lysozyme from solutions has been studied by the atomic force microscopy method. The surface morphology and the growth kinetics of several faces of the orthorhombic and monoclinic modifications of lysozyme crystals are considered. The surface images are obtained at molecular resolution. For the (010) face of orthorhombic lysozyme, the phenomenon of the surface reconstruction is established-doubling of the unit-cell parameter along the a-axis. The main growth parameters of lysozyme are determined the kink density at steps, probabilities of the attachment and detachment of building blocks, the kink and step velocities, and the dependence of the fluctuation in the step position on time.
