Motivated by Ooguri and Vafa, we study superstrings in flat 4 in a constant self-dual graviphoton background. The supergravity equations of motion are satisfied in this background which deforms the = 2 d = 4 flat space super-Poincare algebra to another algebra with eight supercharges. A D-brane in this space preserves a quarter of the supercharges; i.e. = 1/2 supersymmetry is realized linearly, and the remaining = 3/2 supersymmetry is realized nonlinearly. The theory on the brane can be described as a theory in noncommutative superspace in which the chiral fermionic coordinates θα of = 1 d = 4 superspace are not Grassman variables but satisfy a Clifford algebra.
