Sequences of B-chain of insulin determine folding behavior
September 27th, 2004
Sequences of B-chain/domain 1-10/1-9 of insulin and insulin-like growth factor 1 determine their different folding behavior. "Although insulin and insulin-like growth factor-1 (IGF-1) belong to one family, insulin folds into one thermodynamically stable structure, while IGF-1 folds into two thermodynamically stable structures (native and swap forms). We have demonstrated previously that the bifurcating folding behavior of IGF-1 is mainly controlled by its B-domain," scientists in China report. "To further elucidate which parts of the sequences determine their different folding behavior, by exchanging the N-terminal sequences of mini-IGF-1 and...
