چکیده

Octamethylcyclotetrasiloxane (OMCTS), a common constituent of household products, triggers the transformation of bismuth to the volatile toxic derivative trimethylbismuth by Methanosarcina barkeri, which is a representative member of the sewage sludge microflora. Comparative studies with the ionophores monensin and lasalocid, which induce effects similar to those observed for OMCTS, indicated that the stimulation of bismuth methylation is not specific for the siloxane and suggested that the stimulation observed is mainly due to facilitated membrane permeation of the metal ion.

Heme biosynthesis in Methanosarcina barkeri via a pathway involving two methylation reactions.

The methanogenic archaeon Methanosarcina barkeri synthesizes protoheme via precorrin-2, which is formed from uroporphyrinogen III in two consecutive methylation reactions utilizing S-adenosyl-L-methionine. The existence of this pathway, previously exclusively found in the sulfate-reducing delta-proteobacterium Desulfovibrio vulgaris, was demonstrated for M. barkeri via the incorporation of two ...

Differential in vitro methylation and synthesis of the 480-kilodalton corrinoid protein in Methanosarcina barkeri grown on different substrates.

The 480-kDa corrinoid protein was significantly methylated in extracts of acetate- but not methanol-grown cells incubated with 14CH3OH, in part because of its decreased synthesis in cells grown on substrates other than acetate. In addition, a 200-kDa corrinoid protein was methylated in extracts of methanol- but not acetate-grown cells.

Inhibition of methanogenesis by interaction of aluminium ion with co-factor, F-420, in Methanosarcina barkeri.

Methane emission was inhibited by aluminium ion in paddy fields. Addition of Al3+ (20 mM) to the culture medium containing cells of pure Methanosarcina barkeri, inhibited methanogenesis. Methanogenic co-factor, F-420, was isolated and purified from Methanosarcina barkeri MS. Spectrophotometric and spectrofluorometric analysis of interaction between co-factor, F-420, and Al3+ revealed that they ...

Differences in hydrogenase gene expression between Methanosarcina acetivorans and Methanosarcina barkeri.

Methanosarcina acetivorans C2A encodes three putative hydrogenases, including one cofactor F(420)-linked (frh) and two methanophenazine-linked (vht) enzymes. Comparison of the amino acid sequences of these putative hydrogenases to those of Methanosarcina barkeri and Methanosarcina mazei shows that each predicted subunit contains all the known residues essential for hydrogenase function. The DNA...

Conservation of structure in the human gene encoding argininosuccinate synthetase and the argG genes of the archaebacteria Methanosarcina barkeri MS and Methanococcus vannielii.

The DNA sequences of the argG genes of Methanosarcina barkeri MS and Methanococcus vannielii were determined. The polypeptide products of these methanogen genes have amino acid sequences which are 50% identical to each other and 38% identical to the amino acid sequence encoded by the exons of the human argininosuccinate synthetase gene. Introns in the human chromosomal gene separate regions whi...
