The structure of hemocyanin II from the horseshoe crab, Limulus polyphemus. The amino acid sequence of the second largest cyanogen bromide fragment
PQ Behrens, H Nakashima, E Yokota and AF Riggs
Fourteen fragments have been isolated from hemocyanin component II of
Limulus polyphemus by cleavage with CNBr. The amino acid sequence of the
largest fragment, CNBr Ia has been reported (Yokota, E., and Riggs, A. F.
(1984) J. Biol. Chem. 259, 4739-4749). The amino acid sequence of the 12
smaller fragments is reported in an accompanying paper (Moore, M. D.,
Behrens, P. Q., and Riggs, A. F. (1985) J. Biol. Chem. 261, 10511-10519).
We have determined the amino acid sequence of the second largest fragment,
CNBr Ib. The fragment contains 142 residues and has a molecular weight of
16,095.
