CRYSTAL STRUCTURE OF A NON-PSYCHROPHILIC TRYPSIN FROM A COLD-ADAPTED FISH SPECIES.

The structure was published by Schroder, H.K., Willassen, N.P., and Smalas, A.O., in 1998 in a paper entitled "Structure of a non-psychrophilic trypsin from a cold-adapted fish species." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.7 Å and deposited in 1997.

The experimental data on which the structure is based was also deposited.

This PDB entry contains multiple copies of the structure of TRYPSIN.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule has more than one probable quaternary state observed. For more details see the quaternary structure page.
