title: N-terminal amino acid sequence analysis of the subunits of pea photosystem I.
abstract: Six 'core' subunits of pea photosystem I have been isolated and their N-terminal amino acid sequences determined by gas-phase or solid-phase sequencing. On average more than thirty residues were determined from the N-terminus of each polypeptide. This sequence analysis has revealed three polypeptides with charged N-terminal regions (21, 17 and 11 kDa subunits), one polypeptide with a predominantly hydrophobic N-terminal region (9 kDa subunit), one polypeptide which is cysteine-rich (8 kDa subunit) and one which is alanine-rich (13 kDa subunit).
