A revision of the N-terminal structure of sialoglycoprotein D (glycophorin C) from human erythrocyte membranes.
The amino-acid sequence of the N-terminal tryptic glycopeptide of a minor sialoglycoprotein (component D, glycophorin C) from human erythrocyte membranes was re-investigated and revised at the positions 12, 44, 47 and 48. Based on these and previous (Dahr, W. et al., Eur. J. Biochem. 125, 57-62, 1982) studies, the fragment exhibits the following structure (one-letter-code for amino acids, + = glycosylation): (Formula: see text).
