Comparison of the sequence of purified plastidial AGPase SSU with the predicted sequences of other AGPase SSUs. The purified plastidial SSU protein from wheat endosperm was subjected to MALDI analysis, and the sequence of two fragments was obtained by Q-ToF analysis. These sequences were compared with those of other SSUs available in databases. The corresponding sequences of the four SSUs that matched most closely to those of the purified plastidial SSU protein from wheat are shown. The positions of the amino acids in the wheat endosperm AGPase SSU are indicated. Leu (L) and Ile (I) have the same mass and are therefore indistinguishable by Q-ToF. For L and I in the Q-ToF sequence, the amino acid most likely to be present was determined by comparison with other deduced sequences and is shown on the top line with the alternative, less likely amino acid shown below in parenthesis. Rice, Rice seed (AAK27313); Maize, maize embryo (AAK39640); Chickpea, unknown source tissue (AAK27720); Wheat (AGP.S.1b), wheat endosperm (P30523).
