Isolation and Characterisation of a Reserve Protein from the Seeds of Cereus jamacaru (Cactaceae)

We describe here the isolation and characterisation of a major reserve protein from the seeds of Cereus jamacaru. (Cactaceae). This protein has a molecular mass of 5319 kDa and was isolated by a combination of gel filtration chromatography and reverse phase HPLC. The amino acid composition of the pr...
