Cadaverine (1,5-diaminopentane) is a major source of many industrial polyamides such as nylon and chelating agents. Currently, cadaverine is produced by the microbial fermentation of glucose to lysine, which is then decarboxylated by lysine decarboxylase (CadA). However, utilizing CadA for cadaverine production causes enzyme instability. In order to stabilize the CadA homo-decamer structure for in vitro decarboxylation reaction, mutants are designed. Of the four disulfide bond mutants in the… CONTINUE READING
