WARNING: THE PEPTIDES B AND C MEDIATING INTERMOLECULAR CONTACTS BETWEEN 3 TRYPSIN MONOMERS HAVE BEEN ASSIGNED RESIDUE TYPE UNK. THEY HAVE HIGH B-FACTORS AND ARE INTENDED AS PLACE HOLDERS FOR WHAT WE BELIEVE IS A MIXTURE OF BASIC PROTAMINE PEPTIDES, POLYAMINES, AND OTHER COMPOUNDS FROM THE SALMON PROTAMINE EXTRACT, PROBABLY IN MULTIPLE CONFORMATIONS. SIMILAR CAVEATS APPLY TO THE PHENOL ENTITIES WE BELIEVE ORIGINATE FROM IMPURITIES IN THE PROTAMINE EXTRACT USED AS A CRYSTALLIZATION ADDITIVE.
