Effect of cosolvents on the stabilization of bioactive peptides from bovine milk alpha-casein.

abstract：:Hop is a tetratricopeptide repeat domain (TPR)-containing co-chaperone that is able to directly associate with both Hsp70 and Hsp90. Previous data showed that the TPR2A-domain is the primary site for dimerization and that the TPR2B-domain may also play a role in dimerization. We present Hop-D456G, a mutant within the ...
