Sometimes, however, in the new convention, the + sign may be omitted
resulting in ambiguity.
PROTEIN DATA BANK
Since the determination of the three dimensional structures of myoglobin
and hemoglobin as previously mentioned in Chapter 2, many other three
dimensional structures of numerous proteins have been analyzed by X-ray
diffraction studies, NMR measurements, theoretical predictions, etc. Most
of these structures are available from the Protein Data Bank at website
