  DOI：10.1021/ja00066a044

  日期：1993.6

  Gas-phase basicities of 22 dipeptides that contain valine were measured by a double bracketing method in a Fourier transform ion cyclotron resonance spectrometer. Matrix-assisted laser desorption was used to generate protonated peptide ions which were reacted with reference compounds to bracket the gas-phase basicity. In addition, neutral peptide molecules were formed by substrate-assisted laser desorption

• Characterization of Theanine-Forming Enzyme from<i>Methylovorus mays</i>No. 9 in Respect to Utilization of Theanine Production

  For development of theanine production from glutamic acid and ethylamine by coupling yeast sugar fermentation as an ATP-regenerating system, several strains were selected from among about 200 methylamine- and/or methanol-assimilating bacteria depending on the theanine-forming activity of their permeated cells. The amount of theanine formed by the cells of the selected strains was much larger than that by the cells of Escherichia coli AD494 (DE3) expressing Pseudomonas taetrolens Y-30 glutamine synthetase (GS), which has been found to be a usable enzyme for theanine production. A GS-like enzyme responsible for the theanine-forming reaction was obtained from an obligate methylotroph isolate, Methylovorus mays No. 9. The enzyme was induced by methylamine in the culture medium. A molecular mass of 410–470 kDa was obtained by gel filtration of the enzyme, and 51 kDa by SDS–PAGE analysis. The enzyme showed high activity toward methylamine rather than ammonia, which indicates that it is similar to known γ-glutamylmethylamide synthetase. The isolated enzyme also had high reactivity to ethylamine in a neutral pH range, and formed theanine from glutamic acid and ethylamine in a reaction mixture containing a yeast sugar fermentation system for ATP-regeneration.

  为了开发以酵母糖发酵为 ATP 再生系统，从谷氨酸和乙胺中生产茶氨酸的方法，我们从大约 200 种甲胺和/或甲醇同化菌中挑选了几种菌株，这取决于它们渗透细胞的茶氨酸形成活性。所选菌株细胞形成的茶氨酸量远大于大肠杆菌 AD494（DE3）表达假单胞菌 Y-30 谷氨酰胺合成酶（GS）的细胞形成的茶氨酸量。从一种必须的甲基营养体分离物 Methylovorus mays No.该酶由培养基中的甲胺诱导。通过凝胶过滤获得的酶的分子质量为 410-470 kDa，通过 SDS-PAGE 分析获得的分子质量为 51 kDa。该酶对甲胺而非氨表现出较高的活性，这表明它与已知的γ-谷氨酰甲酰胺合成酶相似。分离出的酶在中性 pH 值范围内对乙胺也有很高的反应活性，并能在含有酵母糖发酵系统的反应混合物中将谷氨酸和乙胺生成茶氨酸，以进行 ATP 再生。
