Biotransformation of lysine into cadaverine using barium alginate-immobilized Escherichia coli overexpressing CadA.

abstract：:Unfolded protein response (UPR) usually happens when expressing heterologous proteins in high level, which may help cells to facilitate protein processing. Here, we evaluated the effects of the UPR activator HAC1p on a raw-starch hydrolyzing α-amylase (Gs4j-amyA), so as to improve heterologous production of the enzyme...
