  1. In the “Genotype” column the three transgenic genotypes here analysed are reported. The “Expected N-terminal sequence” column reports the deduced N-terminal amino acid sequences on the basis of transgene nucleotide sequences, whereas the “Observed N-terminal sequence” corresponds to those obtained after Edman degradation, relatively to each of the eight protein spots indicated in the second column.
