"Proteu00ecna cry modified process to increase its sensitivity, polinucleotu00ecdeo, chimeric gene, vector, host plant, part of a plant.Seeds of a plant and the production process ". The present invention is the degradation of the proteins of Bacillus thuringiensis Cry in the digestive tract of mammals.It is the object of Bacillus thuringiensis Cry proteins whose sequ00b3u00eancia peptide was modified in order to make them sensitive to the specific enzymes of the digestive tract of mammals.In particular, the pepsinas. According to this invention, the cry proteins are modified by insertion of sites of enzymatic degradation by pepsin in his sequ00b3u00eancia peptide.The present invention also deals with plants that express these proteins processed cry modified.
