Abstract: Discretization of phase portrait of one 3-dimensional biochemical kinetics dynamical system with piecewise linear right-hand sides of special form is constructed. We describe geometry of this phase portrait and construct there a piecewise linear invariant surface bounded by a stable cycle which is composed by eight rectilinear segments.

Keywords: gene network modeling, positive and negative feedbacks, phase portraits of dynamical systems, cycles, invariant surfaces, the Poincare map, projective transformations.
