摘要
DsbA and DsbC, members of the thioredoxin super-family of redox proteins, which are expressed in the periplasmic space of Escherichia coli, were cloned into and successfully secreted from Brevibacillus choshinensis at similar to 100 mug ml(-1). Both proteins were active in exchanging disulfide bonds of bovine insulin in vitro. Furthermore, DsbA secreted by B. choshinensis promoted the conversion of non-native human epidermal growth factor to the native form.
