Dynamics of immobilized and native Escherichia coli dihydrofolate reductase by quasielastic neutron scattering.
The internal dynamics of native and immobilized Escherichia coli dihydrofolate reductase (DHFR) have been examined using incoherent quasielastic neutron scattering. These results reveal no differenceExpand

Comparative characterization of bovine testicular hyaluronidase and a hyaluronate lyase from Streptococcus agalactiae in pharmaceutical preparations.
Although bovine testicular hyaluronidase (BTH) has been used in several medical fields for many years, these drugs are poorly characterized. We compared pharmaceutical BTH preparations (Neopermease,Expand

Isoenzyme-specific differences in the degradation of hyaluronic acid by mammalian-type hyaluronidases
Bovine testicular hyaluronidase (BTH) has been used as a spreading factor for many years and was primarily characterized by its enzymatic activity. As recombinant human hyaluronidases are nowExpand

Direct determination of vibrational density of states change on ligand binding to a protein.
The change in the vibrational density of states of a protein (dihydrofolate reductase) on binding a ligand (methotrexate) is determined using inelastic neutron scattering. The vibrations of theExpand
