In this paper the X-ray emission spectrum from the nearest to the quasar 3C 273 inner jet knot A was investigated by the kinetic equation method. It is shown that the inverse Compton scattering of the quasar radio emission is responsible for the X-ray emission of the knot. Under certain conditions it is possible to determine the position of the low-frequency break in the spectrum of the quasar using the X-ray radiation of its jet.
