Differential equation model to study dynamic behaviour of globular proteins. 1984

P K Ponnuswamy, and R Bhaskaran

By regarding the globular proteins as spheroidal shaped bodies of uniform density, a differential equation model to study their low amplitude fluctuations was developed. It was then applied to the crystal structures of pancreatic trypsin inhibitor and ferrocytochrome c. The results were tested by comparing them with those of the dynamic simulation and temperature factor studies on the same proteins.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014359	Trypsin Inhibitor, Kazal Pancreatic	A secreted KAZAL MOTIF-containing serine peptidase inhibitor that inhibits TRYPSIN. It is a protein composed of 56 amino acid residues and is different in amino acid composition and physiological activity from the Kunitz bovine pancreatic trypsin inhibitor (APROTININ). It protects against the trypsin-mediated premature activation of ENZYME PRECURSORS in the PANCREAS. Mutations in the SPINK1 gene are associated with CHRONIC PANCREATITIS.
