Denaturation of bovine spleen galectin-1 in guanidine hydrochloride and fluoroalcohols: structural characterization and implications for protein folding.

abstract：:Studies were performed in the rat liver to examine whether or not insulin as well as glucagon causes the induction of mitochondrial serine:pyruvate aminotransferase (SPTm) [EC 2.6.1.51] and if so, whether the mechanisms of induction are similar or different for the two hormones. Not only glucagon but also insulin indu...
