摘要

采用放射肺量测定法研究了不同奈瑟菌对谷氨酸和富马酸的分解代谢。尽管已知脑膜炎奈瑟菌、淋病奈瑟菌和灰奈瑟菌缺乏体外苹果酸脱氢酶活性,但三羧酸循环在所有测试物种中都起作用。结果表明苹果酸的氧化与吡啶核苷酸无关。在磷酸盐的存在下,谷氨酸的氧化不太完全。在脑膜炎奈瑟菌、黄叶奈瑟菌、黄叶奈瑟菌、亚黄奈瑟菌和内酰胺奈瑟菌中,在谷氨酸缺失的情况下,富马酸的分解代谢缓慢且不完全。

Radiorespirometric studies in genus Neisseria. 2. The catabolism of glutamate and fumarate.
The catabolism of glutamate and fumarate was studied by radiorespirometry in selected Neisseria species. The tricarboxylic acid cycle is functioning in all species tested, in spite of the known absence of in vitro malate dehydrogenase activity in N. meningitidis, N. gonorrhoeae and N. cinerea. The results imply a pyridine nucleotide independent oxidation of malate. The oxidation of glutamate is less complete in the presence of phosphate. In N. meningitidis, N. perflava, N. flava, N. subflava and N. lactamica the catabolism of fumarate was slow and incomplete in the absence of glutamate.
