A 2.8-kb HindIII fragment, containing three open reading frames, has been cloned and sequenced from Clostridium litorale. The first gene grdA encoded the selenocysteine-containing protein PA of the glycine reductase complex, a protein of 159 amino acids with a deduced molecular mass of 16.7 kDa. The second gene (grdB) encoded the 47-kDa subunit of the substrate-specific selenoprotein PB glycine that is composed of 437 amino acids. The third gene contained the 5'-region of the gene for… Expand
Two closely linked genes encoding thioredoxin and thioredoxin reductase in Clostridium litorale
Enzyme assays revealed that Gly-31 was not responsible for the observed incompatibility with the E. coli thioredoxin reductase, but it was essential for activity of the thiOREDoxin system in C. litorale. Expand
Expression of the Oenococcus oeni trxA gene is induced by hydrogen peroxide and heat shock.
It was concluded that the trxA gene encodes a functional thioredoxin, and the protein encoded by the cloned fragment was able to complement Escherichia coli strains lacking a functionalThioredoxins. Expand
Factors and Selenocysteine Insertion Sequence Requirements for the Synthesis of Selenoproteins from a Gram-Positive Anaerobe in Escherichia coli
UGA readthrough of SECIS elements present in Desulfomicrobium baculatum (hydV), Treponema denticola (selD), and Campylobacter jejuni (selW-like gene) was considerably enhanced in the presence of E. acidaminophilum selB and selC, indicating recognition of theseSECIS elements and might open new perspectives for heterologous selenoprotein synthesis in E. coli.

Barriers to heterologous expression of a selenoprotein gene in bacteria
The results demonstrate that the selenocysteine-specific UGA codon is readily suppressed under conditions where the homologous SelB protein is absent and that apart from the specificity of the SelB-mRNA interaction, a structural compatibility of the quaternary complex with the ribosome is required.

Fast purification of thioredoxin reductases and of thioredoxins with an unusual redox-active centre from anaerobic, amino-acid-utilizing bacteria.
It is suggested that these thioredoxins might form an evolutionarily separate group in anaerobes studied, based upon their distinguishing features. Expand
Sarcosine reductase of Tissierella creatinophila: purification and characterization of its components
Initial steps for the purification and preliminary characterization of the sarcosine-specific, substrate-binding protein Bsarcosine component of T. creatinophila indicated the involvement of a 50-kDa protein, which indicates that this subunit is the primary site of acetyl transfer from acetyl phosphate.

An algorithm for identification of bacterial selenocysteine insertion sequence elements and selenoprotein genes
A bacterial SECIS consensus model was developed, the key feature of which is a conserved guanosine in a small apical loop of the properly positioned structure that was used to build a computational tool, bSECISearch, for detection of bacterialSECIS elements and selenoprotein genes in sequence databases.

Whole genome sequencing of a novel, dichloromethane-fermenting Peptococcaceae from an enrichment culture
Bacteria capable of dechlorinating the toxic environmental contaminant dichloromethane (DCM, CH2Cl2) are of great interest for potential bioremediation applications. A novel, strictly anaerobic,Expand
Selenium-dependent growth of Treponema denticola: evidence for a clostridial-type glycine reductase
Findings strongly support the notion that T. denticola ferments amino acids via the activity of glycine reductase, an enzyme previously thought to be restricted to gram-positive bacteria. Expand
Tissierella creatinophila sp. nov., a gram-positive, anaerobic, non-spore-forming, creatinine-fermenting organism.
Based on the phenotypic and phylogenetic distinctiveness of the new isolate, it is proposed that the bacterium be classified as a new species of the genus TISSierella, Tissierella creatinophila sp. Expand
