Methanogenic archaebacteria respond to osmotic stress by accumulating a series of organic molecules which function as compatible solutes. In two strains of marine methanogenic archaebacteria, Methanogenium cariaci and Methanococcus thermolithotrophic

Accumulation of compatible solutes, by uptake or de novo synthesis, enables bacteria to reduce the difference between osmotic potentials of the cell cytoplasm and the extracellular environment. To examine this process in the halophilic and halotolera

Turnover of the nitrogen moiety from free amino acid pools in two thermophilic methanogens, Methanobacterium thermautotrophicum delta H and Methanococcus thermolithotrophicus SN1, has been monitored with 15N NMR spectroscopy. In cells growing exponen

The unusual compound beta-aminoglutaric acid (beta-glutamate) has been identified by 13C nuclear magnetic resonance spectroscopy in soluble extracts of marine methanogenic bacteria. We examined several methanogen species representing nine genera and

Trimethyl glycine (glycine betaine) was detected by 13C nuclear magnetic resonance spectroscopy at high intracellular concentrations in several methanogens (Methanogenium cariaci, "Methanogenium anulus" AN9, Methanohalophilus zhilinae, Methanohalophi

The replacement of Arg-54 by Ala in the active site of Escherichia coli aspartate transcarbamoylase causes a 17,000-fold loss of activity but does not significantly influence the binding of substrates or substrate analogs (Stebbins, J.W., Xu, W., & K

Methanohalophilus strain FDF1, a member of the halophilic genus of methanogens, can grow over a range of external NaCl concentrations from 1.2 to 2.9 M and utilize methanol, trimethylamine, and dimethyl sulfide as substrates for methanogenesis. It pr

2,3-Diphosphoglycerate (2,3-DPG) has been found to be the product of the enzymatic degradation of cyclic 2,3-diphosphoglycerate (cDPG) in the archaebacterium Methanobacterium thermoautotrophicum delta H. Although 2,3-DPG has not previously been detec

Methanosarcina thermophila, a nonmarine methanogenic archaebacterium, can grow in a range of saline concentrations. At less than 0.4 M NaCl, Ms. thermophila accumulated glutamate in response to increasing osmotic stress. At greater than 0.4 M NaCl, t

13 C- and 15 N-NMR spectroscopy have been used to identify β-aminoglutaric acid (β-glutamic) as a major soluble component of the thermophilic, autotrophic marine methanogen Methanococcus thermolithotrophicus . This rare, non-protein amino acid has
