Temporal Change in Nitrous Oxide and Dinitrogen from Denitrification Following Onset of Anaerobiosis
UNLABELLED To survive a dynamic host environment, Mycobacterium tuberculosis must endure a series of challenges, from reactive oxygen and nitrogen stress to drastic shifts in oxygen availability. The mycobacterial Lsr2 protein has been implicated in reactive oxygen defense via direct protection of DNA. To examine the role of Lsr2 in pathogenesis and physiology of M. tuberculosis, we generated a...
Dimethylamine was formed from trimethylamine in soils of different pH values. The rate of disappearance of the secondary amine from soil was affected by pH and was markedly reduced under anaerobiosis. The accumulation of dimethylamine in cultures of Micrococcus sp. provided with trimethylamine depended on the nitrogen sources available to the bacterium but was not greatly influenced by the C-N ...
We have isolated two cDNA clones for potato {Solatium tuberosum L. cv. Kennebec) alcohol dehydrogenase (ADH, EC. 1.1.1.1) from a tuber cDNA library (1). Each clone encodes a polypeptide of 380 amino acids that differ at only one position (amino acid 5). The nucleotide sequences show 96% identity These two sequences are highly similar with the sequence of another potato ADH cDNA clone (1) and th...
