Superisometries of the adS*S Superspace
  We find the superisometry of the near-horizon superspace, forming the superconformal algebra. We present here the explicit form of the transformation of the bosonic and fermionic coordinates (as well as the compensating Lorentz-type transformation) which keeps the geometry invariant. We comment on   i) the BPS condition of the branes in adS background and   ii) significant simplification of superisometries of the gauge-fixed Green-Schwarz action in adS(5)*S(5) background.
