The capital letters mark sequence segments (cf. Fig. 15.12).
The numbers give the positions that the amino acids at the beginning of the line occupy in the total sequence. The segments of recurring sequences are ar

ranged

according to the best possible homology. (–:space to maximize homology) Cysteine residues (

) are marked in bold type.


The numbering of the HMW subunits (5 and 9) corresponds to Figs. 15.8 and 15.9.
