Abstract
Dinitrogenase reductase-activating glycohydrolase (DRAG), involved in the regulation of nitrogenase activity in Rhodospirillum rubrum, is associated with chromatophore membranes in cell extracts. We show that DRAG can be specifically released by treatment with MgGDP; other nucleotides studied had no effect. The DRAG activity released corresponds to the release of DRAG protein.
摘要
双氮酶还原酶激活糖水解酶（DRAG）参与了深红红螺菌中固氮酶活性的调节，在细胞提取物中它与载色体膜相关联。我们发现，用MgGDP处理可特异性释放DRAG；所研究的其他核苷酸则无此作用。释放出的DRAG活性与DRAG蛋白的释放相对应。
