Purification and properties of rabbit trypsin

Area of Science:

• Biochemistry
• Enzymology
• Protein Chemistry

Background:

• Trypsin is a key digestive enzyme.
• Understanding enzyme structure and function is crucial in biochemistry.
• Affinity chromatography is a powerful purification technique.

Purpose of the Study:

• To purify rabbit pancreatic trypsin.
• To characterize its physical, chemical, and immunological properties.
• To compare it with other trypsin enzymes.

Main Methods:

• Affinity chromatography using Trasylol-Sepharose.
• Physical and chemical characterization of the purified enzyme.
• Immunological cross-reactivity studies.

Main Results:

• Rabbit pancreatic trypsin was successfully purified.
• The enzyme is a single polypeptide chain.
• It showed immunological cross-reactivity with porcine trypsin but not rabbit acrosomal proteinase.
• Sequence homology was observed at the amino terminus with other mammalian trypsins.

Conclusions:

• Rabbit pancreatic trypsin shares characteristics with other mammalian trypsins.
• Its purification and characterization provide insights into enzyme structure-function relationships.
