From fresh brown pumpkin seeds, two proteins with a molecular mass of 12kDa and an N-terminal sequence rich in arginine and glutamate residues were obtained. The protein designated alpha-moschin closely resembled the fruitfly programmed-cell death gene product and the protein designated beta-moschin demonstrated striking similarity to prepro 2S albumin in N-terminal sequence. alpha- and beta-moschins inhibited translation in the rabbit reticulocyte lysate system with an IC(50) of 17 microM and 300nM, respectively.
