Item Description

The number of strands in the sheet. If a given range of residues bulges out from the strands, it is still counted as one strand. If a strand is composed of two different regions of polypeptide, it is still counted as one strand, as long as the proper hydrogen- bonding connections are made to adjacent strands.
