    • The invention provides an isolated formate dehydrogenase (FDH) polypeptide specific for NADP+and an isolated FDH polypeptide having an adenine ribose recognition loop comprising a first large amino acid and a second amino acid, wherein the first and second amino acid are arranged in space to allow the second amino acid to bond with a phosphate group. Also provided is a variant of an BAD+specific FDH polypeptide, wherein the adenine ribose recognition loop has been mutated at least one position to alter the three dimensional polypeptide structure of the adenine ribose recognition loop to allow a phosphate group to be recognised. The polypeptides of the invention can be used in the conversion of NADP+to NADP or in the conversion of BAD+ to NASH.
    • 本发明提供了对NADP +特异的分离的甲酸脱氢酶(FDH)多肽和具有包含第一大氨基酸和第二氨基酸的腺嘌呤核糖识别环的分离的FDH多肽,其中第一和第二氨基酸排列在 允许第二个氨基酸与磷酸基团结合。 还提供了BAD +特异性FDH多肽的变体,其中腺嘌呤核糖识别环已被突变至少一个位置以改变腺嘌呤核糖识别环的三维多肽结构以允许磷酸基被识别。 本发明的多肽可用于将NADP +转化成NADP或将BAD +转化成NASH。
