Chemical modification of bovine pancreatic trypsin inhibitor for single site coupling of immunogenic peptides for NMR conformational analysis.

J. Biol. Chem. 264(14) , 7882-8, (1989)

Procedures for chemical modification of bovine pancreatic trypsin inhibitor (BPTI) to allow site-specific coupling of immunogenic peptides are reported. Each of the modified proteins has a single free...

Chemical modulation of the chaperone function of human alphaA-crystallin.

J. Biochem. 144(1) , 21-32, (2008)

alphaA-crystallin is abundant in the lens of the eye and acts as a molecular chaperone by preventing aggregation of denaturing proteins. We previously found that chemical modification of the guanidino...
