Abstract

The classical glycolytic pathway contains an NAD-dependent glyceraldehyde-3-phosphate dehydrogenase, with NADP-dependent forms reserved for photosynthetic organisms and archaea. Here, the cloning, expression, purification, crystallization and preliminary X-ray analysis of an NADP-dependent glyceraldehyde-3-phosphate dehydrogenase from Helicobacter pylori is reported; crystals of the protein were grown both in the presence and the absence of NADP.

摘要

经典糖酵解途径包含一种依赖NAD的3-磷酸甘油醛脱氢酶,而依赖NADP的形式则存在于光合生物和古细菌中。本文报道了幽门螺杆菌中一种依赖NADP的3-磷酸甘油醛脱氢酶的克隆、表达、纯化、结晶及初步X射线分析;该蛋白晶体在有和没有NADP的情况下均已生长出来。
