英文摘要
Rat brain glutamate decarboxylase (GAD) isozyme having molecular weight of 65,000 was expressed in Saccharomyces cerevisiae having a specific activity of 50 nmol/min/mg. The expressed enzyme reacted with anti-GAD65 monoclonal antibody and showed a 65 kDa band on SDS-PAGE and Western blot analysis. Detailed culture conditions were examined.Human histidine decarboxylase (HDC) is a close relative of GAD.In order to compare the substrate specificity of two decarboxylases, we have expressed HDC in Saccharomyces cerevisiae. The expression system exhibited 200 pmol/min/mg histamine producing activity which is far superior than any tissue samples. SDS-PAGE analysis gave 74 kDa band corresponding to precursor form of HDC.The expression system we have developed will provide strong hand on further progress in characterizing decarboxylases.
