[Comparison of amino acid sequences of sturgeon triprotamines using protamines from Acipenser stellatus gonads as an example].
The amino acid sequence of the triprotamine stelline C from mature sperm nuclei of Acipenser stellatus has been established by automated sequence analysis of the protein and from data provided by thermolysine peptides. The complete amino acid sequence of stelline C is: R-R-R-R-R-H-A-S-T-K-L-K-R-R-R-R-R-R-R-H-G-K-K-S-H-K. The comparison of the primary structure of stelline C with that of other triprotamines from Acipenser stellatus shows that they are similar except for the absence of N-terminal alanine in the stelline A molecule. The main structure difference between stelline C and other fish protamines is that the stelline C molecule begins with five arginine residues.
