Load the structure of papain, select all hetero atoms and
<BR>
then select the complement of this selection. The purpose
<BR>
of this trick is to exclude all hetero atoms from selection.
<BR>
(ignoring solvent molecules which follow the structure),
<BR>
extract the sequence and copy it to the reference buffer.
<BR>
After that, load the structure of human cathepsin B, select
<BR>
chains A and B (each cathepsin B contains two chains), extract
<BR>
the sequence and compare it with the content of the reference
<BR>
buffer. The segment width is 10 and the minimal score is 8.
